Join our teamHeating, Ventilation and Air Conditioning (HVAC) systems aim to regulate, heat, cool, ventilate, clean or dehumidify the indoor air quality (IAQ) within the vehicle cabin. HVAC systems consist of sensors and mechanical/electronic switches in the frontend and blower motors, actuators (for fresh air circulation control, air-flow control, and temperature control), and refrigeration units to transfer air to the cabin within the backend to ensure thermal comfort for drivers and passengers.
NXP provides a broad family of Arm® Cortex® -M-based MCUs (S32K) with motor control libraries to cover a wide range of needs in this application space. Additionally, NXP offers motor control-integrated solutions for a cost-effective, small footprint system solution for most HVAC applications. The broad portfolio of S12 MagniV® devices combines MCU with SBC functionalities, network connection and motor control specific drivers in a single package and are supported by a library of motor control algorithms.

Arm® with Digi: HVAC using Kinetis® MCUs
The need for graphical user interfaces in industrial and consumer applications is steadily increasing. For instance, LCDs are now on appliances such as washers, dryers, refrigerators, and stoves, allowing enhanced human control. Security and HVAC control systems are other examples of applications that require advanced graphical display interfaces to enable human control of the various system functions. Along with the LCD, the use of touch screens is also increasing. To address this need, NXP®
This application note describes Flap Motor Control Based On HVAC Platform
AN4704: This application note describes the design of a 3-phase brushless DC (BLDC) motor control drive using a sensorless algorithm. The design is targeted at automotive applications. This cost-effective solution is based on the NXP® Semiconductors MC9S12ZVML128 chip, which is dedicated to automotive motor control. The design exhibits the suitability and advantages of the MC9S12ZVML128 microcontroller for motor control. It serves as an example of a BLDC control design using NXP’s 16-b
This application note describes the design of a three-phase sensorless BLDC motor drive with back-EMF zero-crossing. It is based on NXP’s MC9S12G240 MCU that can be effectively used for motor control applications.
MC9S08LG32 MCU is used to implement HMI function in HVAC platform solution, and it communicates via SPI with MC9S12G240 MCU which utilizes other HVAC functions.
