Product Validation according to AEC-Q100/101 Description The TLE985x product family is part of the Infineon Embedded Power IC portfolio. The single chip 2-phase motor driver integrates the industry standard Arm Cortex-M0 core with an NFET driver. This System-on-Chip solution includes four fully integrated NFET drivers optimized to drive a 2-phase motor via four 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.
