14
COM
Motor middle point connection.
15
COMIN
Motor position detection comparator filter
pin. A capacitor must be connected between
this pin and the FIL pin (pin 16).
16
FIL
Motor position detection comparator filter
pin. A capacitor must be connected between
this pin and the COMIN pin (pin 15).

VREG
Regulator voltage (5V) output.
A capacitor must be connected between
these pins and ground.
VCC
VREF

18
F/R
Motor rotation direction switching. A
high-level input causes current to flow into
the motor in the order of U, V, and W and a
low-level input in the order of U, W, and V.
Changing the order of current application
turns the motor in the opposite direction.

Forward signal
Forward/reverse
switching signal
19
PWMIN
PWM signal input pin.
"H" The output transistor is turned on by the
level voltage input. "L" The output transistor
is turned off by the level voltage input, and
the motor stops. The speed of the motor is
controlled by controlling Duty of the input
signal. When the pin opens, the motor
becomes all velocities.
20
SOFTST
Soft start time setting.
The motor can be started smoothly by
connecting a capacitor between this pin and
ground.
