COM
Motor middle point connection.

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.

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.

CTL
Motor control voltage input.
When the control voltage is higher than 3V
(3V
< CTL voltage), the motor stops.
The motor speed is controlled by varying the
control voltage within the range of 3V to 1V
(3V
> CTL voltage > 1V). When the control
voltage becomes lower that 1V (1V
> CTL
voltage), the current limit set by the RF
resistor is reached.
20
MINSP
Minimum speed setting voltage input.
The minimum speed of the motor can be set
by resistor-dividing the regulator voltage and
feeding the resultant voltage that is within the
range of 1V to 3V (1 V
< MINSP < 3V).
