LIN based relay Drive ICs TLE984xQX

The TLE984x product family brings together the ARM® Cortex®-M0 core and the market proven peripherals of its predecessor TLE983x (XC800 based relay driver). It integrates on a single die all the necessary functions to sense, control and actuate a motor via a relay or via a PN MOSFET Half-Bridge. Produced on Infineon’s first-in-industry automotive qualified 130nm Smart Power technology, the Infineon Embedded Power System-on-Chip solution offers an unmatched level of integration as well as system cost to performance optimization for the target application segments.

The TLE984x family offers scalability in terms of Flash memory sizes ranging from 36kB to 64kB with pin-compatible devices. It is specifically designed to fit to a wide range of LIN-slave motor control applications such as window lifts, wipers, sun roofs, fans and blowers to name a few. The new Infineon® Embedded Power IC is supported by a complete development tool chain provided by Infineon and third party vendors. The tool chain includes compiler, debugger, evaluation board, LIN low level driver and configuration tool as well as various software code examples.
