BM64300MUV 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. It detects a rotor position by 3 Hall sensors. In addition, silent and low vibration operations are implemented by making the output current a sine waveform.
