BM64070MUV Datasheet (ROHM) - Three-phase Brushless Motor Pre-driver

BM64070MUV, Three-phase Brushless Motor Pre-driver

BM64070MUV is the pre-driver IC of sine wave drive for three-phase brushless motor driver that supports 48 V power supply controlling the motor driver constructed in external FETs.

The sensor-less drive that the hall devices for the position sensing are unnecessary is adopted.

It has a speed feedbac
