Infineon TLE9893-2QTW62S

TLE98932QTW62SXUMA1 is a microcontroller with CAN-FD and NFET driver for BLDC applications. It is a fully integrated 3-phase motor driver with the industry standard Arm^® Cortex^®-M3 core, enabling the implementation of advanced motor control algorithms. It includes a bridge driver to drive upto six external power NFETs for 3-phase motor control. A dual-stage charge pump enables low voltage operation and programmable charge current profile along with adaptive MOSFET control for optimized EMC. Its peripheral set includes a current sense amplifier, two successive approximation ADCs that can be synchronized with the capture and compare unit 7 for PWM generation, and several 16bit timers. A CAN-FD transceiver and MULTICAN+ controller is integrated as well to enable CAN-FD communication along with a number of general-purpose I/Os. It includes an on-chip linear voltage regulator to supply external loads.
