Relay Driver IC with Integrated ARM Cortex M0 Core

The TLE984x product family from Infineon 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.

Features include: Two protected low-side switches (min. 270mA); Up to two protected high-side switches (min. 150mA); Up to five high-voltage inputs with wake up functionality; Integrated LIN transceiver compatible with LIN 2.2 and SAE-J2602; Two full duplex serial interface (UART) with LIN support; Two synchronous serial channel (SSC), compatible with SPI; On-chip oscillator and PLL for clock generation; the Measurement unit includes 8-bit ADC module with 7 multiplexed inputs for system supervision, 10-bit ADC module with 13 multiplexed inputs and On chip temperature and battery voltage measurement; Independent programmable window watchdog; 5V/1.5V Internal supplies; External Supply (VDDEXT): 5V+/-2% at 20mA; Power saving modes include MCU slow-down Mode, Sleep Mode, Stop Mode and Cyclic wake-up from Sleep Mode or Stop Mode.

System benefits include: System-on-Chip solution with integrated ARM® Cortex® for DC motor control; Platform solution for a size and weight optimized relay based motor control; Integrated voltage regulator, LIN transceiver, switch inputs and relay driver; Cyclic Sense and Cyclic Wake-up capability saves average current consumption; Minimum number of external components reduce BOM cost; PG-VQFN package with 7 x 7mm footprint enables PCB space saving; and Single chip solution improves module reliability.
