Product Introduction
MS39545It is a sensorless three-phase DC motor driver chip that adoptsSinusoidal drive mode, featuring low noise and low vibration.There is a speed control pin to control the motor speed. And the power supply voltage can be as low asto4Vto adapt and adjust the motor speed.MS39545adoptsSOP8PPpackage, with heat sink.
