2 FIL
LV8805V
Function
Motor middle point connection.
Motor position detection comparator filter
pin. A capacitor must be connected between
this pin and the FIL pin (pin 2).
Motor position detection comparator filter
pin. A capacitor must be connected between
this pin and the COMIN pin (pin 5).
VG

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

F/R
8 PWMIN
No connection. These pins are not
connected with the internal parts.
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.
VREG
7
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.
Reverse signal
15kΩ
100kΩ
Forward signal
VREG

Forward/reverse
switching signal
10 SOFTST
Soft start time setting.
The motor can be started smoothly by
connecting a capacitor between this pin and
ground.
