Rotational Direction Control
The forward and reverse rotational direction is controlled by FWD (pin 14), and REV (pin 15) inputs. Conditions are as
follows.

Motor Speed Control
- The almost maximum torque is obtained when it is used with the pins 13 (CTL) open.
- If the torque of the motor is too low, then the applied voltage at pins 13 (CTL) is 0[V].
- When motor speed controlled, the applied voltage of the pins 13 (CTL) is between 0 and 4V.
Also, if speed control is constant , the applied voltage of the pins 13 (CTL) is between 4 and 5V.
- This IC's applied maximum voltage is 6V when V
CC
is 8V.
- You must not use the applied CTL voltage above 5.8V when Vcc is 8V, and 3V when V
CC
is 5V.
