3-phase brushless motor
pre-driver
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.
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.

13) Motor Lock Protection circuit (MLP circuit)
There is built-in motor lock protection circuit (Motor Lock Protection: MLP), ON/OFF of MLP circuit and OVLO
threshold can be set from LPE terminal. Monitor Hall signals, when the LPE = "H" or "M", if Hall signal logic does not
change to 1.1sec(Typ), driver outputs will all be locked as "L". Latch can be released via standby status or through
switching BRKB/CW logic. Moreover, when PWMB = "H" or open state is detected for about 15ms, latch can be
released by rising and falling edges of subsequent PWMB. However, when LPE = "L", when short brake action
(including switching rotation direction) enables or TSD circuit works, MLP circuit doesn't work. And LPE terminal is
pulled up by VREG through a resistance of 50k(Typ)±15 k.

14) Pre-driver output
Driving signal is output to external output power transistor through drive signal generated from internal logic output
drive signal is output for external power supply transistor. Driving voltage of upper gate is VG voltage (Vcc+7V(Typ))
and driving voltage of lower gate is VREG voltage (5V(Typ)). In addition, a dead time (1µs(Typ)±30%) is designed
between driving signals of upper gate and lower gate in order to prevent upper and lower FET from being set to ON
synchronously when PWM is rectified synchronously. Due to the influence of the motor’s counter electromotive force,
the output feedback terminal might swing under GND potential. When excessive current occurs (about over 30mA),
incorrect action or even damage might be caused. Therefore, please insert a resistor of about 100~ 510 before
putting into use. Moreover, we recommend you to use output feedback terminal with a slow rate of over 50ns.
15) Control signal sequence
Though we recommend you input control signals of ENB, CW, PWMB, BRKB and LPE terminals after inputting VCC,
if input control signals before inputting VCC, there won’t be any problem. If LPE terminal is set to "H" or "M" when
being started, please be informed that if motor rotation cannot be detected within the set time (edge of FG signal
cannot be input), then the MLP circuit starts and motor fails to start. Moreover, the order of priority is set to control
signal and IC internal signal. Please refer to the following table.
