General Description

BM62350MUV is the pre-driver IC of sine wave drive for

three-phase brushless motor driver that supports 24 V

power supply controlling the motor driver constructed in

external FETs. It detects a rotor position by 3 Hall sensors.

In addition, it has a speed feedback control function, and

controls output PWM Duty by adjusting the rotational

frequency characteristics for the input PWM signal and

the rotational frequency affected from motor.
