Infineon TLE9877QXW40XUMA1, 32bit ARM Cortex M3 Microcontroller, Cortex, 40MHz, 64 kB, 48-Pin VQFN

MOTIX™ TLE9877QXW40 offers reliable solutions for automotive applications such as pumps and fans

The MOTIX™ TLE9877QXW40 is part of the MOTIX™ TLE987x product family. The MOTIX™ TLE9877QXW40 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 behaviour. 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-Q100 Grade 0 automotive qualified device enabling cost and space efficient solutions for mechatronic BLDC motor drive applications that are located under-the-hood such as pumps and fans.
