BLDC Motor Driver
MS39747TEA
Three-phase sensorless motor driver
Datasheet Download
Overview
The MS39747A is a three-phase motor driver IC, which incorporates sensorless sinusoidal wave drive, and can minimize fan vibration when applied to most of fan drives. Sensorless control eliminates the need of hall sensor for fan application.
The MS39747A has a flexible closed-loop speed control system. EEPROM can customize fan speed curve according to specified application. IC can be used without microprocessor after programming.
