Product Validation according to AEC-Q100/101 Description TLE985x devices integrate an Arm Cortex-M0 processor and peripherals for motor control, power supply and communication. Two integrated measurement units (analog-to-digital converters) for monitoring temperature, battery voltage and four monitoring inputs help to save pins. These inputs can be operated directly with battery voltage, which saves costs on additional components such as external voltage dividers or Datasheet 2 Rev. 1.0 2019-07-26
