NXP Semiconductors has introduced two high-speed CAN (HS-CAN) transceivers, TJA1042 and TJA1051, for HS-CAN applications up to 1 Mbit/s. Improved ESD performance (±8kV according to IEC 61000-4-2) allows manufacturers to build electronic control units without having to incorporate external ESD protection.
The transceivers disengage from the bus when they are not powered on or are operating in a low power mode, resulting in current consumption as low as 10 mA typical for effective automotive power management with reduced CO2 emissions.
Predictable under-voltage behavior simplifies the design of systems that incorporate Start-Stop functionality, according to Toni Versluijs, NXP senior director and general manager CAN/LIN Transceivers. Both transceivers are RoHS-compliant and do not contain halogenated flame retardants (Dark Green).
“These new transceiver products from NXP enable our customers to introduce greener, safer and more reliable cars with reduced system costs,” Versluijs said.
The ISO 11898-2 compliant transceivers have been qualified to AEC Q-100.
Sion Power Corporation and BASF SE are collaborating to accelerate the commercialization of Sion Power‘s proprietary lithium-sulfur (Li-S) battery technology for the electric vehicle (EV) market and other high-energy applications.
The collaboration is focusing on development of battery materials to improve Li-S battery life, increase the energy density, and thus extend the driving range of EVs beyond what is currently available with alternative rechargeable battery technologies.

ABI Research expects global penetration rates for telematics services in new cars to reach 12% in 2010 and 43% in 2014.
“With GM‘s OnStar and Ford‘s SYNC to be joined by telematics solutions from Toyota and Chrysler launching later this year, the US remains the most competitive (telematics) market,” said ABI Research practice director Dominique Bonte. “At the same time Toyota and GM will expand into the Chinese market, while government regulation in Brazil and the EU will drive uptake in Latin America, Western and Eastern Europe.”
Safety and security features such as emergency calling (eCall), breakdown assistance (bCall) and remote diagnostics remain the most popular, but connected infotainment such as off-board navigation, online local search, concierge services, and Internet access offered by OEMs such as BMW are enjoying increasing interest, according to ABI.
While embedded aftermarket solutions offered by companies such as LoJack and OCTO Telematics remain popular in specific markets for stolen vehicle tracking and PAYD insurance, new affordable portable and converged consumer telematics are bringing features such as geofencing, speed monitoring and basic diagnostics to a wider audience.
ABI Research expects that by offering multiple safety, cost and entertainment benefits to different stakeholders such as governments, car manufacturers and dealers, and end-users, consumer telematics will become a standard automotive feature in developed regions by 2015. However, this evolution will require the removal of barriers such as high cost and long development cycles. Standardization initiatives such as the Next Generation Telematics Protocol (NGTP) and the adoption of open source automotive software development platforms supported by the recently announced GENIVI consortium will help.

Hitachi, Ltd. and Hitachi Vehicle Energy, Ltd. have developed a lithium-ion battery with power density of 4,500 W/kg, which is 1.7 times the output of the company’s mass-produced, automotive lithium-ion batteries. Sampling of the new battery will start this fall.
To reduce internal resistance, the battery employs a new manganese cathode and an original Hitachi battery structure. Hitachi said that for the same energy density, a lithium-ion battery has about half the volume and weight of a nickel hydrogen battery, and about one-third the volume and weight of a lead battery.
In 2000, the Hitachi Group developed and mass-produced a lithium-ion battery for automotive applications. A second-generation lithium-ion battery with a power density of 2,600 W/kg is currently being delivered for on-board automotive applications. A total of some 600,000 cells have been delivered, mainly to car manufacturers and railway companies.
Development of a third-generation lithium-ion battery with a power density of 3,000 W/kg has been completed. That battery will go into mass-production in 2010.
The fourth-generation battery set to start sampling this fall is smaller and lighter yet able to provide 4,500W/kg output. The new battery will be on display at the Automotive Engineering Exposition 2009 held at PACIFICO Yokohama from May 20 to May 22.
austriamicrosystems has introduced the AS5163, a magnetic rotary encoder IC designed to satisfy automotive requirements in angle sensing applications such as throttle or gas-pedal systems where robust IC protection is essential.
The chip incorporates both +27 Volt overvoltage protection and -18 Volt reverse polarity at supply pins. An intelligent short circuit monitoring function protects it against damage under short circuit conditions.
Andreas Pfingstl, austriamicrosystems’ product manager for automotive encoders, said the AS5163 offers a single-wire interface and can be configured for 14-bit digital, 12-bit PWM, or ratiometric analog output. It can also be customized to cover any system specific angle range by setting a start and end position of the rotational movement.
The AS5163 is operational over an ambient temperature range from -40°C to 150°C. It is available in a TSSOP 14 package and operates at 5V supply voltage.
SMSC said Hyundai has selected SMSC’s MOST networking technology as part of the infotainment system for the Hyundai EQUUS. Hyundai also uses MOST in its Genesis sedan and in the Kia Mohave.
The EQUUS, currently the top of the line Hyundai model available in South Korea, also includes Vehicle Stability Management, a Lane Departure Warning System, and an Adaptive Front Lighting System.
Taoglas has introduced the PA-25 “Anam,” a six-band, surface-mount antenna that delivers efficiency of over 50% on all bands in a 36×6x5 mm ceramic design suited for automotive applications.
The multi-band cellular antenna covers all worldwide cellular bands including 850/900/1700/1800/1900 and 2100Mhz for GSM, CDMA, DCS, PCS, WCDMA, UMTS, HSDPA, GPRS and EDGE.
“The PA-25 is the result of years of intensive research and development into high grade ceramic formulas and getting lower cellular bands designed into small form factors,” said Dermot O‘Shea, Director, Taoglas. Applications include telematics, vehicle diagnostics, and remote monitoring.
ON Semiconductor has introduced the NSI45 series of two-terminal linear constant current regulators for driving current in automotive and other LED lighting applications.
Dan Huettl, director and general manager for ON Semiconductor’s Small Signal Division, said the constant current regulators are based on patent-pending, self-biased transistor technology. By regulating voltage over a wide range, the devices ensure constant brightness over the operating voltage range. The series is designed with a negative temperature coefficient to protect LEDs from thermal runaway at extreme voltage and operating temperatures.
The NSI45 series is offered in 20 milliamp (mA), 25 mA and 30 mA device options in SOD-123 and SOT-223 packages. The devices are available in ±10% and ±15% steady-state regulated current (Ireg) tolerance. The series is rated at 45 V with operating temperature range of -40 °C to 85 °C and maximum junction temperature of 150°C. The SOD-123 is a 3.7 mm x 1.6 mm x 1.2 mm surface mount package that can dissipate 230 milliwatts (mW) of power at 85°C with 500 mm /1 ounce copper on the board. The SOT-223 is a 7.0 mm x 6.5 mm x 1.6 mm surface mount package that dissipates 630 mW of power at 85°C with 500 mm /1 ounce copper on the board and is ideal for extreme thermal operating environments. The devices are qualified to AEC101. The devices are lead-free RoHS compliant and use halogen-free mold compound.
The NSI45 in SOD-123 package is priced at $0.0545 per unit in 10,000 quantities. The NSI450 in SOT-223 package is priced at $0.090 per unit in 10,000 quantities.
