Datasheet Download
Overview
The MS39549/MS39549D and the MS39545/MS39545D are threephase sensorless DC motor drivers with low noise and vibration, which adopt sinusoidal drive mode.Motor speed can be controlled by VSP/PWM pin. And the voltage can be as low as 4V to adapt or adjust the motor speed.The MS39549 and the MS39545 are available in SOP8/PP packages with thermal pad. The MS39549D and the MS39545D are available in DFN8 packages with thermal pad.
