Relay Driver IC with Integrated Arm® Cortex® M0
LIN based MOTIX™ Relay Driver ICs provide scalable motor control solutions
The MOTIX™ TLE984x product family brings together the Arm® Cortex®-M0 core and the market proven peripherals. 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 MOTIX™ Embedded Power mixed-signal MCU offers an unmatched level of integration as well as system cost to performance optimization for the target application segments.
Our MOTIX™ Relay Driver ICs offer 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.

QM-parts in Functional Safety Applications (ASIL)
Infineon's MOTIX™ Embedded Power ICs are developed as QM-parts, but nonetheless can be and are already used in a variety of motor control application that require Functional Safety (ISO26262) up to ASIL-B such as but not limited to Window Lift (ASIL-A), Sunroof (ASIL-A), Auxiliary pumps (ASIL-B) or Engine Cooling Fan (ASIL-B).
Infineon offers the following design-in support for its Embedded Power ICs:
- FIT data information (ISO26262)
- Function/Blocks vs. Area Breakdown
If these data is required, please contact your local Infineon partner who can provide you with these information.
