New MOTIX MCU Embedded Power IC-Families with CAN FD Interface for Faster Communication and Higher Performance

Infineon Technologies AG has introduced the TLE988x and TLE989x families of MOTIX MCU-embedded power integrated circuits. These new offerings integrate a gate driver, microcontroller, communication interface, and power supply onto a single chip, resulting in compact system-on-chip solutions. This advancement aims to deliver improved performance, and the new families feature CAN (FD) as the communication interface.

The new devices in the TLE988x and TLE989x families utilize B4 or B6 bridge N-channel MOSFET drivers, an Arm Cortex M3 microcontroller, and a CAN (FD) controller and transceiver capable of achieving a communication speed of 2 Mbps. This setup ensures rapid and robust communication and provides high computing performance due to the high system frequency (60 MHz) and its dual flash enabling read-while-write operation.

The families offer a significant boost in processing power compared to their predecessors, the TLE987x product family. This advancement is accompanied by functional safety and cybersecurity capabilities, crucial for use cases like electric vehicle thermal management systems involving oil pumps.
