General Description
BD63005AMUV is a Three-Phase Brushless Motor Driver with a 33V power supply voltage rating and a 2A (3.5A peak) output current rating. It generates a driving signal from the Hall sensor and drives PWM through the input control signal. In addition, the power supply can use 12V or 24V and it has various controls and built-in protection functions, making it useful for variety of purposes. Since the IC adopts small packages, it can be used on small diameter motors.
