The IC families integrate essential elements such as gate drivers, microcontrollers, communication interfaces, and power supply into a single chip, offering a minimized footprint and enhanced performance.


Infineon Technologies have launched the TLE988x and TLE989x families extending the company’s portfolio of MOTIX microcontroller unit (MCU) embedded power ICs. The company claims that these products have been designed with a minimized footprint, combining essential components such as gate driver, microcontroller, communication interface, and power supply all on a single chip. By integrating these features, the families provide an enhancement in performance, offering a streamlined solution for various applications. These AEC Q-100-qualified ICs are suitable for automotive brushed DC and brushless DC motor control applications in body, comfort, and thermal management. The IC families offer fast, robust communication and high computing performance. Operating at 60 MHz with dual flash, they include read-while-write functionality.

The driver family supports up to 256 kB flash and 175°C, and features Adaptive MOSFET Control, with an algorithm that optimizes electromagnetic induction (EMI) and power, ensuring consistent switching. The embedded power ICs are backed by a comprehensive ecosystem, including software and a 150 W coolant pump reference design. The company also offers Automotive Software Process Improvement Capability dEtermination (ASPICE) qualified motor control libraries and commercial software to simplify design and evaluation.

The key specifications of the embedded ICs include:

  • Single power supply from 5.5 V to 28 V
  • 32-bit Arm Cortex -M3 core at up to 60 MHz
  • Temperature Range TJ: -40°C up to 175°C
  • FLASH0 up to 32 KB, FLASH1 up to 256 KB with EEPROM emulation
  • RAM up to 32 KB
  • 3-phase bridge driver with charge pump 
  • Safe switch-off path 

“The new MOTIX MCU embedded power IC families address our customers’ needs for the smallest integrated smart motor control solutions with fast and very robust on-chip CAN FD transceivers for host communication; the new product families additionally offer approximately 60 percent more processing power compared to predecessor family and provide functional safety and cybersecurity functions which are becoming increasingly important for oil pumps in thermal management systems in electric vehicles,” said Andreas Doll, Senior Vice President and General Manager Smart Power at Infineon.
