3-Phase Brushless Motor Driver
BD63005MUV
General Description
BD63005MUV is a 3-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.
