BM62380MUV
General Description
BM62380MUV is sine wave driver IC for three-phase
brushless motor driver with 40 V power supply voltage
rating and 2.0 A output current rating. It detects the 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.
Features
Speed Control on PWM Duty Input
Low ON Resistance DMOS Output
Built-in Boost Voltage Circuit
3 Hall Sine Wave Drive
Automatic Lead Angle Control
Motor Pole Select Function
Soft Start Function
Current Limit Function
Power Save Function
Direction of Rotation Setting
Short Brake Control
Speed Feedback Control
Able to set Motor Rotation Speed Table and Various
Parameters with the built-in OTP
Built-in Several Protection Functions (Motor Lock
Protection [MLP], High Speed Rotation Protection,
Over Voltage Lock Out [OVLO], Under Voltage Lock
Out [UVLO], Thermal Shutdown [TSD], Over Current
Protection [OCP])
