BM62350MUV
BM62350MUV is Three-Phase Brushless Motor Pre-Driver manufactured by ROHM.
DC Brushless Motor Driver Series
Built-in Speed Control, 3 Hall Sensors Three-Phase Brushless Motor Pre-Driver
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.
