BD63002MUV
●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.
