RDS12GHVAC: S12G Automotive HVAC Control Platform

Overview

The NXP® S12G automotive HVAC platform reference solution uses the scalable S12G 16-bit MCU family with MC33905, MC33932 and MC33937 analog devices to drive stepper, DC and BLDC motors and provide a feature-rich solution for automotive HVAC applications.

  • Consists of a central control board with (HMI, a motor control board, flap and blower motors
  • Enables basic functions of an auto HVAC using temperature, light, humidity and air quality sensing interfaces with configurable automatic climate control software algorithm to efficiently control vehicle climate
  • Reduces overall design effort, shortens time to market and can be tailored for both 12V and 24V systems

Features

  • Three types of motor control sensorless BLDC DC stepper motor
  • Automatic climate control
  • Supports multiple temperature zones
  • Ultra low power mode, can be woken up by HMI or LIN CAN bus
  • CAN and LIN communication interfaces
  • 3x3 matrix keypad and two encoder knob inputs
  • 4x37 segment LCD and adjustable backlighting
  • Sensor interfaces for temperature, light, humidity and air quality available
  • Two logic relay interfaces to compressor defrost module
  • Real-time clock and date display, adjustment for calendar
  • Extensible with touch keyboard or touchscreen board
  • Suitable for both 12 volt and 24 volt HVAC systems
