Refrigerators often use a damper to control airflow and a fan to provide circulation. While discrete solutions have been used for years, this reference design uses integrated motor drivers that provide easy control, high performance and full protection. DRV8848 drives the stepper motor damper and DRV10983 drives the BLDC fan with quiet 180° commutation. The BLDC has closed-loop speed control, using MSP430G2553 and DRV8812 for a PWM-based power supply. The design uses a single-layer PCB. BLDC and stepper control example code is provided in the MCU firmware. Protection from over-current, over-temperature and under-voltage are all integrated in the DRV devices.
