The G32M3101 Motor Control SoC features a 64MHz Arm® Cortex®-M0+ core, a 40V 3P+3N gate driver, and a 5V/60mA LDO to simplify system design. Its built-in DIV/MULT arithmetic unit speeds up algorithm execution, supporting both sensor-based and sensorless FOC control. With versatile peripherals, it ensures precise motor control, signal processing, and communication, making it suitable for fans, water pumps, air purifiers, pedestal fans, and personal care devices.
