Überblick

Infineon`s H Bridge Driver IC family enables maximum functional safety and comfort features for the target applications

Infineon has combined its wealth of experience in motor control drivers for automotive applications with all the benefits of an industry-standard core. The unique result, our 3rd Generation Embedded Power IC based on Arm® Cortex®-M cores, addresses a wide range of smart 2-Phase DC motor control applications like, sunroof, power window lift, electrical pumps, electrical fans.

Produced on Infineon’s first-in-industry automotive qualified 130nm Smart Power technology, the Infineon Embedded Power System-on-Chip solutions offer an unmatched level integration and system cost to performance to optimization for the target application segments.

The TLE986x family offers scalability in terms of Flash memory sizes and MCU system clock frequency supporting a wide range of motor control algorithms. It uses the same MCU and peripherals as the TLE987x family, 3-Phase driver, enabling design synergies between DC and BLDC motor control applications.

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 example software code for Motor Control.
