ROHM Semiconductor
General Description
BD63002MUV is pre-driver of 3-phase brushless motor. It generates a driving signal from the Hall sensor and drives PWM through the input control signal. Since there is a built-in booster circuit, Nch-Nch MOS transistors can be used on the external power transistor. In addition, the power supply can use 12V or 24V and it has various controls and protection functions built-in, making it useful for a variety of purposes. Because it adopts small packages, it can also be used on small diameter motors.
FEATUREs
◾ Built-in 120° commutation logic circuit.
