H-Bridge Driver IC with Integrated Arm® Cortex® M3
Infineon's MOTIX™ H-Bridge Driver IC family enables maximum functional safety and comfort features for the target applications
The MOTIX™ TLE986x and TLE988x families address a wide range of smart 2-Phase DC motor control applications like sunroof, window lift, electrical pumps, electrical fans. Additionally, it offers scalability in terms of flash memory sizes and MCU system clock frequency supporting a wide range of motor control algorithms.
Moreover, TLE988x family is developed according to ISO26262 providing ASIL B features and some variants have built-in cybersecurity.

- High system frequency (60 MHz) and dual flash (read-while-write)
- Smallest fully integrated motor control solution with CAN FD
- ISO 26262 compliance (ASIL B) and context segregation (layered access right management)
- Infineon’s patented Adaptive MOSFET Control (AMC) feature
- Premium design-in support with software, tools and services
The new TLE988x devices use a B4 bridge N-channel MOSFET driver, an Arm® Cortex® M3 microcontroller, and a CAN (FD) controller and transceiver supporting a communication speed of 2 Mbps. Customers benefit not only from fast and robust communication but also from the highest computing performance.

QM-parts in Functional Safety Applications (ASIL)
Infineon`s 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.
