Single-Phase DC BLDC Motor Drive Module

This module adopts self-developed dedicated high-performance SOC chip integrated with Arm Cortex-M0+, pre-driver and LDO. External N+P MOSFETs can be matched to build drive modules of different power levels. It features wide operating voltage range, simple peripheral circuits, high efficiency, low noise and low power consumption.

The fully self-developed motor drive control algorithm software supports flexible analog voltage speed regulation and PWM speed regulation for BLDC motors. It is equipped with functions including soft start, soft commutation, stall protection with auto-restart, overcurrent protection, current limiting and closed-loop speed control. Customized functions are available on demand. The proprietary software algorithm supports forward and reverse rotation with fixed Hall sensor positions, eliminating the need for Hall position calibration.
