Atmel to Launch Ultra Low-power RF Transmitter IC for Car Access, TPMS Apps

(Product News, 22 Apr 2008)

Atmel Corp. will be exhibiting its latest driver and RF transmitter ICs at the coming 4th China International Automotive Electronics Products and Technologies Show and Summit (AES) in Shanghai on May 19 to 21, 2008.

Atmel will also demonstrate its latest products for automotive applications, including body electronic solutions (stand-alone control function devices, high-temperature driver ICs, a LIN family of transceivers, System Basis Chips and System-in-Package solutions, as well as CAN devices), automotive AVR microcontrollers, automotive RF solutions for car access and tire-pressure monitoring systems (TPMS) as well as general-purpose serial EEPROMs.

In addition, the company will launch the ATA6837 and ATA6839 high-temperature hex half-bridge driver ICs designed for passenger car as well as for 24V truck applications, and the ATA5749 programmable, ultra low-power RF transmitter IC for car access and TPMS applications.

The ATA6837 and ATA6839 have an operating chip temperature of 200°C and are able to dissipate approximately twice the power of conventional driver ICs, which can normally only work up to 150°C chip temperatures.

The fully integrated fractional-N PLL RF transmitter IC ATA5749 is one of the very few automotive RF transmitter ICs that is fully programmable, thus enabling flexible system design and adaptation. Moreover, it is one of only a few such devices with ultra low power consumption—a significant factor for TPMS applications. Its active current consumption in transmission mode is about 20 percent less than the values of currently available solutions on the market.
