Three-Phase Brushless Motor Predriver
BD63001AMUV
General Description
BD63001AMUV is a Three-Phase Brushless Motor
Predriver that uses upper Pch and lower Nch MOS
transistor for an external output power transistor. It
generates a driving signal from the Hall sensor and
drives PWM through the input control signal. In addition,
the supply voltage that can be applied is 12V or 24V, it
has various controls and built-in protection functions,
making it useful for a variety of purposes. Since the IC
adopts small packages, it can be used on small diameter
motors.
