Advanced charging technologies to top $34 billion in 2015

NEW YORK, USA: Markets for advanced charging technologies (including solar-powered handsets, solar chargers, wireless power units, fuel-cell battery charging products and public charging kiosks), worth about $1.5 billion in 2010, are forecast by ABI Research to grow at a robust CAGR of more than 86 percent to exceed $34 billion in 2015.

As people carry and use increasing numbers of portable electronic devices, they have a growing need to charge their batteries on the go. Today’s road warriors can tell you it’s not always feasible to plug a cellphone handset into a wall outlet or car adapter for a quick charge.

That is why a number of vendors are developing and commercializing advanced charging technologies that can top up batteries wirelessly or using solar or wind power, or which provide for a fast download of electricity while waiting for one’s flight.

Research director Larry Fisher of NextGen, ABI Research’s emerging technologies research incubator, says: “With developers about to release advanced charging products in late 2010 and the first half of 2011, the advanced charging revolution is about to take off.

"In addition, the Wireless Power Consortium’s release of the Qi standard for interoperable wireless charging in 2010 has set the stage for portable electronics manufacturers and infrastructure producers such as Panasonic, Philips Electronics, Samsung, LG Electronics and Nokia to incorporate the technology into their products."

Some of these technologies are particularly applicable to users in developing countries. Parts of the Middle East and Africa, for example, do not have access to stable power, and cellphone users must travel many miles and pay to charge up.

Solar chargers and handsets could make a real difference to the lives of people in such circumstances, even though they’re currently being marketed primarily to the eco-conscious in the developed world.

Packaged LED market experiencing tremendous growth with an expected CAGR of 28.2 percent between 2009 and 2015

LYON & PARIS, FRANCE: Yole Développement and EPIC will announce the publication on 15 November 2010 of their new market & technological studies dedicated to LED market and manufacturing technologies:
* Status of the LED industry “SLI 2010”, 2008-2020 analysis.
* LED Manufacturing Technologies “LED ManTech 2010”

This comprehensive survey describes the main market metrics and manufacturing technologies implementing broad adoption of Solid State Lighting.

The packaged LED market is experiencing tremendous growth with an expected CAGR of 28.2 percent between 2009 and 2015. In our base scenario, revenues will reach $8.9 billion in 2010 and grow to $25.7 billion in 2015 and close to $30 billion in 2020.

In terms of volume, LED die surface will increase from 6.3b mm2 to 51b mm2 in 2015, a 41.6 percent CAGR. This will prompt substrate volumes to growth from 12.7M TIE (Two Inch Equivalent) in 2009 to 84.4M TIE in 2015, a 37.1 percent CAGR (smaller than the die surface increase due to significant manufacturing yield improvements). The equipment market will experiment a dramatic growth cycle with demand driving the installation of close to 1400 reactors in the 2010-2012 period.

“Anticipation of future demand and generous subsidies in China will trigger the installation of another 700-1000 reactors in the same period, leading to a short period of oversupply starting in late 2011. However, this oversupply will mostly affect the low end of the market,” explains Tom Pearsall, EPIC.

Growth in general lighting applications will be enabled by significant technology and manufacturing efficiency improvements that will help to lower the cost per lumen of packaged LED to be reduced 10 fold between 2010 and 2020: Economies of scale, LED efficiency improvement, including at high power (droop effect), Improved phosphors, Improved packaging technologies, Significant improvements in LED epitaxy cost of ownership through yield and throughput. However, additional breathoughs are needed; Haitz’s Law is not enough.

White paper on optimizing LED-based recessed downlight apps

MONTREAL, CANADA: A new white paper providing guidelines for developing high-performance solid state downlights is now available from Future Lighting Solutions.

The paper, titled “Enabling LED-Based Recessed Downlight Applications,” describes the considerations and components for implementing LED-based downlight fixtures that meet market needs as well as ENERGY STAR requirements, including light output, efficacy and longevity benchmarks.

Topics covered in the paper include component selection, how to determine the corrected drive parameters, and the role of optical, thermal and power solutions in producing reliable solid state downlighting.

Examples provided utilize Philips Lumileds LUXEON Rebel LEDs, NXP dimmable IC drivers, and Future Lighting Solutions simpleLED light engines that accelerate time to market by providing LEDs, secondary optics and onboard connectors already mounted on circuit boards.

The simpleLED off-the-shelf assemblies also include UL recognition that eliminates the need for a full in-system LED component investigation to obtain UL Listed status for new luminaires.

The paper provides a road map for implementing a Future-developed 4” and 6” reference design for recessed downlight systems.

The attention to downlight applications reflects the fact that downlighting accounts for up to one-fourth of the lighting energy used. LED-based downlights reduce energy consumption by 45% to 80% over conventional luminaires. They also significantly reduce bulb replacements costs because they have longer hours of operation compared to traditional light sources, provide a green RoHS-compliant, and enable far more flexible designs because of their small form factor.

RFMD unveils new family of integrated configurable components

GREENSBORO, USA: RF Micro Devices Inc. has announced a new family of integrated configurable components for multiple markets.

The highly integrated components, comprised of the RFFC207x and RFFC507x product families, perform multiple common RF functions in a reduced footprint while delivering the flexibility necessary to develop radio systems that operate over a wide dynamic range and across a broad range of frequencies and channel bandwidths.

The RFFC207x and RFFC507x product families integrate RFMD's world-class fractional-N PLL/VCO combination with RF mixers to provide radio designers an elegant radio partitioning option with very high performance, superior integration and no compromise in flexibility.

The RFFC207x and RFFC507x represent the second generation of RFMD's innovative RF205x family of integrated configurable components, which enables radio designers across industries to shrink circuit board area, reduce risk and shorten product development time – all of which lower the total cost of radio implementation.

The RFFC207x and RFFC507x expand upon the capabilities of the RF205x family by enhancing performance and extending frequency range to serve even more industries and applications. General purpose in nature, RFMD's newest family of integrated configurable components is applicable to fixed and mobile infrastructure, radio repeaters, super-heterodyne radios, diversity receivers, frequency band shifters, CATV, software-defined radios, point-to-point radios, satcom, VHF/UHF radios, military, industrial and other applications.

The product family's wide bandwidth enables use in multiple systems and applications. The RFFC207x series has a local oscillator (LO) range from 85MHz to 2700MHz, with a 30MHz to 2700MHz mixer on-chip. The RFFC507x series has an LO range of 85MHz to 4500MHz with mixer range extending up to 6000MHz.

With industry-leading integrated phase noise of 0.18deg rms at 1GHz, the RFFC207x and RFFC507x improve system performance for radio designers. Additionally, the integrated fractional-N synthesizer features an advanced sigma-delta modulator to achieve ultra-fine step sizes and lower spurious products, while integrated mixers enable a smaller implementation (5mm x 5mm) than competing solutions.

Finally, by integrating the entire LO path on-chip, the RFFC207x and RFFC507x eliminate the need for designers to work with the highly sensitive interface from VCO to mixer, saving valuable design time and improving end product manufacturing yields.

The RFFC207x and RFFC507x series also deliver industry-low power consumption. The components' bandwidth and phase noise specifications are achieved using only 125mA from a 3-volt supply (single-mixer, high linearity setting), and the current can be reduced to 100mA by reducing the programmable mixer linearity setting. Importantly, the 4500MHz components use only 10mA more than the 2700MHz components.

All of the components can be programmed through a simple 3-wire serial interface. They also feature a unique programming mode that allows up to four devices to be controlled from a common serial bus. By eliminating the need for separate chip-select control lines between devices and host controller, this lowers the cost of implementation and the risk of interference between RF and digital lines on the target PCB.

Finally, two frequencies can be loaded into the device when it is initialized, allowing convenient switching between frequencies, and lock detect and general purpose pins are available, enabling control though the serial bus.

RFMD is showcasing its industry-leading integrated configurable components at the Electronica Tradeshow, in Munich, Germany, November 9-12 at booth #A4.135.

The single-mixer, 2700MHz RFFC2072 starts at $7.00 per 10,000 units, and the single-mixer, 5000MHz RFFC5072 starts at $9.00 per 10,000 units. Samples and evaluation boards are available now, and production quantities are expected to be available by the end of the December 2010 quarter.

Dramatic demand decline pulls down LED price in Q310, down pressure likely to exist in Q4

TAIWAN: LEDinside has released its latest LED price trend report, showing that the LED price plummeted sharply in Q3 2010 due to the sudden decline in the LED application demand including inventory adjustment resulting from less-than-expected large-size panel demand and sluggish lighting application demand.

The LED price for large-size panel application fell around 11-16 percent, while the price for high power LED for lighting application slumped more than 17 percent. As for the mobile application, LED price was roughly flat with about 3-4 percent seasonal erosion thanks to the relatively stable demand.Source: LEDinside, Taiwan.

In light of large and medium-size backlight applications in Q3 2010, under the combined influence of inventory adjustment and weakening LED demand due to worse-than-expected panel shipment, the price of mainstream 5630 LED for TV backlight application lowered about 11 percent, price at $0.17-$0.12. Meanwhile, the LED price for NB and LCD monitor backlight application decreased between 12-16 percent as well.

LEDinside points out that the price of LED products which include 0.4t and 0.6t for mobile backlight applications is expected to remain stable, down around 3-4 percent as a result of the stable shipment.

Regarding the high power LED for lighting applications, the LED price severely slid due to an enlarging supply and demand gap because new projects sluggish and the demand didn’t meet expectations plus new production capacity readiness. The price of mainstream 100-120lm dropped up to 20 percent in Q3.

LED price outlook for Q4 2010
LEDinside predicts that the mainstream product specification might have minor change as Q4 2010 enters the seasonal down cycle although there are new products in developing.

As demand on new type TV backlight is limited and new lighting demand doesn't turn strong, the LED price is estimated to decline near 10 percent under down pressure in Q4 2010.

The market price pressure is expected to stabilize between the end of Q4 2010 and the beginning of Q1 2011, because the demand for shipment of large-size backlight is expecting to picking up. Meanwhile, the demand for LED lighting is expected to rebound.

RFMD expands broadband product portfolio for HFC networks

NEW ORLEANS, USA: RF Micro Devices Inc. announced the expansion of its broadband product portfolio targeting Hybrid Fiber Coax (HFC) transmission network hardware, cable head end, cable hub equipment, and Multi Dwelling Unit/Multiple Tenant Unit (MDU/MTU) equipment.

RFMD expands portfolio of GaN-based CATV components

NEW ORLEANS, USA: RF Micro Devices Inc. announced availability of the RFPD2650, a new gallium nitride-based hybrid power doubler amplifier that delivers industry-best low distortion performance with the flexibility to optimize for supply current or energy consumption.

The RFPD2650 hybrid power doubler amplifier module is specifically designed for CATV infrastructure applications including hybrid fiber coaxial (HFC) optical nodes.

Power doublers are used in HFC networks to extend the range of signal transmission from the head-end to the consumer. To minimize the cost of delivering the signal to the edge of their networks, multi system operators (MSOs) prefer to use as few amplifiers as possible.

MSOs are also increasingly seeking to minimize the operational expenses associated with the HFC network, most notably power consumption and reliability. The RFPD2650 power doubler addresses both of these customer concerns, as does the entire line-up of RFMD's GaN-based amplifiers.

The RFPD2650 supplies a minimum gain of 21dB over the entire 45-1003MHz frequency range. It can deliver up to 20% power or energy savings with no performance penalty in HFC networks, or it can be configured to provide 3dB higher distortion level performance with the same power consumption.

With this unique blend of performance attributes, the RFPD2650 enables MSO system designers to select either industry-leading or energy saving ("green") performance – all while maintaining the ease of use infrastructure OEMs have come to expect from industry-standard SOT115J packaged amplifier modules.

The RFPD2650 leverages GaN HEMT and GaAs pHEMT technology to provide the industry's best distortion performance, enabling longer range transmission. Maximum current is 450mA, and current consumption can be reduced dramatically to less than 370mA for applications requiring reduced distortion performance. Programmed to match the distortion level of competitive devices, RFMD's RFPD2650 delivers two watts of power consumption savings.

The RFPD2650 is available now in sample or production quantities and is priced at $26.50 in quantities of 5,000.

RoHS vs. REACH approach to substance restrictions

Gary Nevison, Premier Farnell

UK: The basis for RoHS and REACH substance restrictions are quite different.

Restrictions in the original RoHS directive were based on hazards - if a substance is hazardous and there are alternatives, then it could be banned REACH restrictions are introduced only if a risk to human health or the environment can be proven, it cannot be controlled and safer substitutes exist.

The original six RoHS restrictions were imposed without a full assessment of the impact of the possible alternatives even though some were not fully tested. It was enough to show that there is a potential risk without evidence of an actual risk. For example, lead is banned by RoHS but there is no evidence that its presence in electronics has, or is, harming human health or the environment (except at end-of-life where unsafe recycling is carried out).

Also, the possible substitutes had not been identified when this restriction was imposed in 2002, and although less hazardous substitute solder alloys have since become available, their impact was not known until some years after the RoHS lead ban.

The impact of lead solder substitutes is now known because the US EPA carried out a life cycle assessment which shows that neither lead solders nor lead-free solders are clear "winners" overall as they each have different properties and impact. Too late for the politicians I fear, but it would have been interesting if this data had been available in 2002.

REACH restrictions are based on lengthy risk assessments that consider research into the impact of the substance in its entire life cycle and also the possible alternatives. This also considers the control measures used by industry to minimise risk and social and economic issues. REACH restrictions are likely to be application specific where a risk is identified, although total bans are also possible.

The other main difference is that RoHS bans substances present in electrical and electronic equipment that fall within the scope of the 8 product categories (currently) of the directive. REACH affects all chemicals including those used to make the equipment (alloys, solvents, paints, etc.) and chemicals present in finished products of all types. There are very few exclusions and exemptions.

In Europe, the industry is starting to prefer the REACH approach and there increasingly appears to be a consensus by both industry, the EC and many politicians that this approach should be used for future RoHS restrictions once the recast enters force.

TV backlight orders see no improvement while revenues of LED vendors generally slipped in September

TAIWAN: Based on the analysis and statistics of LEDinside, a research division under TrendForce, in September this year, listed LED manufacturers in Taiwan have total revenue of 9.736 billion NTD, an 8.1 percent decline compared with August revenue of 10.593 billion NTD and 45.8 percent rise in YoY.The revenue for LED chip manufacturers in September reached 4.554 billion NTD, down 6.9 percent from August. The revenue for LED package manufacturers in September amounted to 5.182 billion NTD, down 9.1 percent from August.

Compiled by LEDinside, LED index (LEDX) observes the industry through the performance of the LED industry market value.Currently, the Chip LEDX is at 4140.9 points, while the Package LEDX has come to 4849.1 points, reflecting a lack of market confidence in the LED industry. September revenue in the LED industry was further widely affected by the inventory problem of LCD TV vendors.

LED backlight market analysis
Although the hot LCD TV sales of National Day Holidays in China is expected to solve part of the inventory problem, most brand vendors only offered low-priced promotion on CCFL TVs.

The sales performance of LED backlit TVs is good as well but it mainly digests the inventory prepared by TV or panel manufacturers in the beginning of Q3. Therefore, for LED industry players, TV backlight orders haven’t improved and most of them still expect the LED backlight TV to grow fast in next year.

LEDinside predicts the LED TV market size will reach 92 million sets in 2011, nearly tripling the 2010 growth. The edge-type LED backlit LCD TV has greater potential than the direct type. It has advantages both in the cost and shape with thinner size.

As for the IT product backlight, WitsView, the other research division under TrendForce, says that due to the panel cost for LCD monitors and notebooks, manufacturers are unwilling to slash price and have waged the price protection battle. Since October, the price has stopped falling. In light of revenue generated by LED manufacturers, as the market, previously over pessimistic about the IT product shipment, has started to revise the shipment forecast, IT product backlight orders for some LED vendors show positive signs.

Revenue of chip manufacturers in September
The revenue of Taiwan’s chip manufacturers in September is observed to slip 6.9 percent from August and rise 55 percent YoY. Total revenue of chip manufacturers in Q3 still grew 11.6 percent compared with Q2.Because of the inventory adjustment by the Korean panel makers, backlight orders for large-sized panels started to suffer from its impact. Besides, as MO source material shortage was tighter and the price of sapphire substrates was rising, profits were shrinking. Various factors led to a small reshuffle in September revenue ranking which had remained stable for over the past six months.

LNAs with multiple gain states optimize HSPA/LTE system performance

SUNNYVALE, USA: Maxim Integrated Products has introduced the MAX2666/MAX2668 low-noise amplifiers (LNAs) for high-data-rate wireless protocols such as HSPA and LTE.

Each LNA features three programmable gain states, allowing customers to dynamically adjust linearity and sensitivity to optimize system performance in the face of varying input-signal strengths.

If interference from adjacent signals is particularly high, as is often the case with mobile devices, the gain can be increased to maintain optimum blocker performance. Ensuring peak system performance regardless of signal conditions, the MAX2666/MAX2668 are well suited for HSPA/LTE-based radio systems such as smartphones and tablets.

Maxim's advanced SiGe BiCMOS process enables these broadband LNAs to combine superior performance characteristics with an ultra-compact footprint. They deliver 15dB of gain; feature a low 1.0dB noise figure for improved receive sensitivity over discrete or CMOS solutions; and operate over the I, IV, V, VI, VII, and X UMTS frequency bands.

Maxim's innovative design enables a tiny package (1.5mm x 1.0mm x 0.55mm), thereby facilitating their use in space-constrained applications such as handheld devices and cellular-based data cards. Only one external component is required to complete the board-level design.

As is common with Maxim's LNAs, customers can expect longer battery life in their end equipment due to low power consumption and low supply voltage. The MAX2666/MAX2668 operate with a low 3.8mA (typ) supply current and less than 100microamps in the lowest gain mode. They run off of a 2.7V to 3.3V supply.

Fully specified over the -40 degrees Celsius to +85 degrees Celsius extended temperature range, the MAX2666/MAX2668 are available in a 6-pin, ultra-thin land-grid array (LGA) package. Prices start at $0.65 (1000-up, FOB USA).

T/R switches integrate clamping diodes to protect ultrasound imaging systems

SUNNYVALE, USA: Maxim Integrated Products has introduced the MAX4936/MAX4937 fully integrated octal high-voltage transmit/receive (T/R) switches. These switches integrate clamping diodes to isolate the low-voltage receive path from the high-voltage transmit path, thus protecting the receiver input from voltage spikes due to leakage currents flowing through the T/R switches.

Maxim's integrated solution uses > 50 percent less board space than discrete circuits while providing high bandwidth, low jitter, and low signal distortion. The MAX4936/MAX4937 are ideal for use in ultrasound imaging and industrial flaw-detection probes, in which board space is at a premium.

The MAX4936/MAX4937 feature eight individually programmable switches controlled through an SPI(TM) interface with a 12-bit shift register and transparent latch. These features simplify device operation when updating the states of the T/R switch; they ensure that all switches are off at power-on; and they reduce noise due to clock feedthrough.

The MAX4936/MAX4937 T/R are based on the conventional diode topology, but include adjustable current biasing through the serial interface. The devices are specified over the 0 degrees Celsius to +70 degrees Celsius commercial temperature range, and are packaged in a small, 5mm x 11mm, 56-pin TQFN. Prices start at $12.00 (1000-up, FOB USA).

IXYS intros largest single die Schottky diode for increased efficiency in power rectification

BIEL, SWITZERLAND: IXYS Corp. announced its successful development of a new range of single Schottky diodes in the MINIBLOC package.

The combination of a new Schottky diode chip design and the MINIBLOCTM packaging offers the designer the highest power and current density that allows permanent currents of 300A with breakdown voltages in the range of 45 volts to 200 volts.

“Our new high power Schottky reduces the need for our customers to use multiple devices in parallel for higher power rectification applications which not only simplifies designs, but increases efficiency and facilitates space saving initiatives,” commented Bradley Green, VP of International Sales of IXYS.

The new DSA300 diode range features lowest on-state losses by design and includes the minimal reverse recovery losses inherent in a Schottky diode construction. Its smooth switching characteristic makes the Schottky irreplaceable in applications that are sensitive to Electromagnetic Interference (EMI) and noise.

IXYS has optimized the design of its in-house Direct Copper Bonded (DCB) ceramic isolation substrate in the MINIBLOC package to provide an extremely rugged and easy to mount solution.

Traditional solutions for high power rectification applications have the necessity to connect two legs in parallel in order to reach high current density. Due to the negative temperature co-efficient and the risk of thermal runaway there is the need to de-rate the operational current by over 20 percent. This new single chip design eliminates the need from competitive sources to reduce the power handling per component and thus using more components which increases system cost and size.

The product range starts with three products (DSA300I45NA, DSA300I100NA and DSA300I200NA) for the voltages classes 45, 100 and 200 Volts.

Common applications for the DSA300 series are output rectification for Switch Mode Power Supplies (SMPS), OR-ing circuits for the paralleling of multiple power supply modules, redundancy OR-ing in UPS, freewheeling diodes and bypass diodes for solar panels.

The use of this highly integrated Schottky diode range also includes industrial power conversion such as welding, battery and capacitor charging circuits, especially solar powered battery chargers.

Universal Display announces significant advances in solution-processible phosphorescent OLED material systems

EWING, USA: Universal Display Corp., enabling energy-efficient displays and lighting with its UniversalPHOLED technology and materials, announced significant advances in the performance of its UniversalP2OLED solution-processible, phosphorescent OLED material systems for use with solution-based manufacturing processes.

Display and lighting manufacturers are evaluating solution-based manufacturing techniques as an additional path for the cost-effective production of large-area OLED displays and lighting devices. These developments were announced during the 10th International Meeting on Information Display (IMID 2010), being held from October 11 to 15, 2010 at the KINTEX in Ilsan, Gyeonggi, Korea.

In a paper, Dr. Kwang Ohk Cheon, Senior Research Scientist at Universal Display, reported that the performance of Universal Display’s solution-processible P2OLED technology and materials have advanced significantly through the continued development of enhanced materials and device structures using its proprietary solution-processed, small-molecular emitter systems. These systems are now approaching the performance of PHOLEDs made by vacuum-evaporated techniques.

During his talk, Dr. Cheon reported on a new green system with 66 candelas per Ampere (cd/A) and 130,000 hours of operating lifetime to 50 percent of an initial luminance of 1000 nits - representing approximately a two times improvement in luminous efficiency and lifetime over Universal Display’s results reported a year ago.

In addition, the company’s red P2OLED system now offers 15 cd/A and 62,000 hours, and its light blue P2OLED offers 18 cd/A and 5,000 hours. These results are achieved without using any burn-in or pre-aging methods.

Through the development of optimized ink formulations, the company has also demonstrated ink-jet printed P2OLED devices with comparable performance to devices made by spin-coating. While spin coating is a technique generally only used for research purposes, ink-jet printing is one of the leading solution-processing candidates for use in large-area manufacturing settings.

“The recent performance advances of our solution-processed, phosphorescent OLED material systems, achieved by our Universal Display team, represent significant progress over the past year,” said Steven V. Abramson, president and CEO of Universal Display.

“Universal Display’s highly energy-efficient PHOLED technology and materials are already considered to be critical to the manufacture of OLED displays and lighting produced by vacuum-based manufacturing processes today. These recent P2OLED results move us a major step closer to enabling the industry to produce energy-efficient OLED displays and lighting devices on larger-area manufacturing platforms by cost-effective, solution-processing manufacturing methods.”

Renesas Electronics intros new control IC for automotive LED headlights

SANTA CLARA, USA: Renesas Electronics Corp., a premier provider of advanced semiconductor solutions, announced the availability of its new control IC (part number μPD168891) for automotive light-emitting diode (LED) headlights.

The main features of the μPD168891 IC are:

(1) an integrated current-control function for constant-current drive of LEDs and a pre-driver function for driving external metal-oxide-semiconductor field-effect transistors (MOSFETs);

(2) integrated protection functions essential for automotive applications, including LED current and external MOSFET overcurrent protection; and

(3) a newly developed compact package with low thermal resistance. The new device can be combined with other devices, such as MOSFETs, Schottky diodes, and choke coils to build electronic-control units for LED headlights in automobiles.

The μPD168891 device is designed to satisfy the requirements of automotive headlight applications by integrating functions required for LED constant-current drive as well as other functions.

Main functions of the control IC:

Integration of functions specifically for automotive LED headlight applications
The μPD168891 device can provide constant-current drive control for up to 12 power LEDs connected in a series. The voltage-boost switching frequency can be set to a maximum of 500 kilohertz (kHz), a rate slightly lower than the AM radio frequency band to prevent interference with the car audio system.

LED drive is supported for power-supply voltages ranging from 6 volts (V) to 28V. An integrated pre-driver circuit can drive two power MOSFETs used for voltage-boost drive and current-line cutoff in case of protection works.

Integration of multiple protection functions
The μPD168891 device incorporates several protection functions including overcurrent protection for the LED current and external MOSFETs, over voltage/load (LED) open protection, LED pin short-circuit protection and overheating protection.

A diagnostic function can output information on the device state when a protection function is triggered by a malfunction, and a shutoff function controls external power MOSFETs to disable current lines. These functions enable a higher-level unit, such as a body control module, to monitor the state of the electronic-control unit and prevent secondary problems due to continuing current flow.

Newly developed compact VQFN package with low thermal resistance
To reduce heat generation and board dimensions, the μPD168891 control IC uses a newly designed compact package (48-pin VQFN, 7×7mm, lead-free) with low thermal resistance, making it possible to build automotive control units that are more compact and lightweight.

Samples of Renesas Electronics' new μPD168891 control IC are currently available. Sample pricing begins at US$5.00 for 100-piece quantities. Mass production is scheduled for first half fiscal 2012.

Comings and goings of RoHS recast

Gary Nevison, Premier Farnell

UK: Progress towards agreement on the proposed RoHS recast has hit troubled waters and a first reading approval now seems unlikely.

Belgium, who holds the EU presidency, has proposed to abandon a list of priority substances which could potentially face restriction. This list includes many of the Substances of Very High Concern (SVHC) on the REACH Candidate List as well as the likes of arsenic compounds, beryllium compounds and PVC.

The original proposal from the European Commission was to include just four SVHCs, but in June the European Parliament’s environment committee voted to expand the list to 37 substances. The latest Belgian proposal states that the original four substances (HBCDD, DEHP, BBP and DBP) should have their risks assessed in the future.

The Belgian proposal does not include a restriction on nanosilver, which had been voted for by MEPs, nor is there any labelling or safety data sheet obligations mentioned previously.

Finally, there is still disagreement over the start date for an “open scope” with Belgium now proposing 2019 (previously 2017) and the European Parliament environment committee wanting all electrical and electronic equipment, unless specifically excluded, covered by 2014.

Discussions are ongoing.
