TIDA-01418描述
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.


特性
  • 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
