Infineon Technologies AG MOTIX™ MCU | 32-bit motor control SoC (system-on-chip) - 3-Phase Bridge Driver IC with Integrated Arm® Cortex® M - TLE9872QXA40 TLE9872QXA40

MOTIX™ TLE9872QXA40 is cost- and performance-optimize d solution for BLDC wiper applications The TLE9872QXA40 is part of the MOTIX™ TLE987x product family. It is a single chip 3-Phase motor driver that integrates the industry standard Arm® Cortex®-M3 core, enabling the implementation of advanced motor control algorithms such as field-oriented control. It includes six fully integrated NFET drivers optimized to drive a 3-Phase motor via six external power NFETs, a charge pump enabling low voltage operation and programmable current along with current slope control for optimized EMC behavior. Its peripheral set includes a current sensor, a successive approximation ADC synchronized with the capture and compare unit for PWM control and 16-bit timers. A LIN transceiver is also integrated to enable communication to the device along with a number of general purpose I/Os. It includes an on-chip linear voltage regulator to supply external loads. It is a highly integrated AEC-Q 100 Grade 0 automotive qualified device enabling cost and space efficient solutions for mechatronic BLDC motor drive applications such as wipers.
