Automotive HVAC compressor module

Block diagram

Overview

Our integrated circuits and reference designs for high-voltage automotive heating, ventilation and air conditioning (HVAC) compressor module applications help you accelerate development through small solutions with intelligent drive capabilities including high-power gate drivers, isolated communication interfaces, power supplies and algorithms.

Design requirements

Automotive HVAC compressor module designs require:

  • Minimized number of isolated components.
  • Reduced EMI to optimize system performance.
  • Comprehensive diagnostics for fault identification.
  • High efficiency and sensorless torque control even at low speeds.

MCU

close

The micrcontroller receives the driver commands, interprets the commands and acts upon the commands by turning on and off the power to the HVAC compressor. The commands are received from HVAC control unit or received via the communication interface.
