Power integrated circuits (ICs) for motor control and thermal management uses introduced by Infineon
MUNICH – Infineon Technologies AG in Munich is introducing the TLE988x and TLE989x embedded power integrated circuits (ICs) for automotive brushed DC and brushless DC motor control applications in body, comfort, and thermal management applications.
The power ICs integrate a gate driver, microcontroller, communication interface, and power supply on one chip for small size, weight, and power consumption (SWaP). The TLE988x and TLE989x families feature CAN (FD) as the communication interface, and are AEC Q-100 qualified.
The devices use a B4 or B6 bridge N-channel MOSFET driver, respectively, an Arm Cortex M3 microcontroller, and a CAN (FD) controller and transceiver supporting a communication speed of 2 megabits per second for motor control uses.
The power ICs offer 60 MHz system frequency, dual flash solid-state memory data storage, are ISO 26262 (ASIL B) compliant, and come in a 7-by-7-millimeter TQFP package. Some variants have built-in cyber security.
The MOTIX MCU TLE988x 2-phase bridge driver family and the MOTIX MCU TLE989x 3-phase bridge driver family include multiple devices with flash volumes as large as 256 kilobytes and support temperature ranges to 175 degrees Celsius.
The ICs feature Infineon's Adaptive MOSFET Control algorithm, which compensates for the variation of MOSFET parameters in the system by adjusting the gate current automatically.
