Relay Driver IC with Integrated Arm® Cortex® M0
LIN based Relay Driver ICs give integrated, scalable and cost efficient solutions for target applications
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 mixed-signal MCU offers an unmatched level of integration as well as system cost to performance optimization for the target application segments.
Our 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.

Applications
Space is of essence for body and comfort applications such as smart window lift or sunroof applications. The ideal fit: A highly integrated mixed-signal MCU at a low price point with a small form factor to save valuable PCB board space. A single chip solution for improved module reliability is also in high demand. For this size and weight optimized relay-based motor control applications, Infineon offers high quality semiconductors.
Our Relay Driver IC with integrated microcontroller is using an automotive qualified Arm® Cortex® M-core. 32-bit core for complex software solutions with Direct Memory Access (DMA) Controller up to 14 channels ensure high performance for applications. Additionally, it offers a small form factor and housing with only 7x7 mm.
What is more, our solutions have a minimum demand of external circuitry. With an integrated voltage regulator, LIN transceiver, and high-and low side switches to drive the relays, the system IC builds a perfect fit for all relevant functions. And with cyclic sense and cyclic wake up capability, the average current consumption can be reduced to gain overall energy efficiency.
Key benefits:
- Reduced cost
- Integrated Relay drivers
- Protection features
Application example: Smart window lift
