Automotive high voltage: high power motor driver reference design for HVAC compressor
Description
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.
Features
- 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 circuitIsolated CAN-communication interfaceIsolated power supplyNon-isolated: low-cost: high- and low-side gate drivers with 2.5A peak outputInstaSPIN: sensorless torque control algorithm"
