Product Introduction
MS4932Nis a three-phase sine-wave brushless DC motor (BLDC) or permanent magnetsynchronous motor (PMSM) controller. This chip processes Hall sensor signals,the controller can implementPWMswitching by switching the three-phase converter. There are twoPWMmodes: sine wave mode and square wave mode.This chip has overcurrent protection, short-circuit protection, overvoltage protection, and overtemperature protection,to protect the chip and motor from damage.
