3-phase brushless motor
pre-driver
BD63000MUV
General Description
BD63000MUV 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.
Driving with Nch-Nch MOS transistors.
PWM control mode (low side arm switching).
Built-in power-saving circuit.
CW/CCW function.
Short brake function.
FG output (Open drain).
Built-in protection circuit for current limiting,
overheating, under voltage, over voltage, motor lock.
Applications
OA machines.
Other general civil equipments.
