Automotive high voltage, high power motor driver reference design for HVAC compressor


Design files


This brushless DC (BLDC) motor reference design controls an automotive HVAC (heating, ventilation, and air conditioning) compressor by using the UCC27712-Q1 high-side and low-side gate driver followed by discrete insulated-gate bipolar transistor (IGBT) half bridges. This reference design uses TI's InstaSPIN software with a three-phase motor control algorithm, which the designer can enable using special libraries in the read-only memory (ROM) of Piccolo microcontrollers (MCUs) and provides expert tools to designers of sensorless (velocity and torque) motor control applications.

  • Low-voltage side survives voltages up to 45V, withstands reverse battery conditions, and withstands load dDump conditions (12V system)
  • Incorporates protection against overcurrent and false turn-on using an active "Miller Clamp" and overcurrent detection circuit
  • Isolated CAN-communication interface
  • Isolated power supply
  • Non-isolated, low-cost, high- and low-side gate drivers with 2.5A peak output
  • InstaSPIN, sensorless torque control algorithm
