Power-supply voltage pin.
V CC voltage is impressed. The permissible operation voltage is from
4.0 to 16.0(V). The capacitor is connected for stabilization for GND pin
(6pin).
Motor drive control input pin.
It shifts from the stand-by state to a prescribed output operation
corresponding to the state of the input when the ENA pin becomes a
standby mode by L, the circuit current can be adjusted to 0, and it makes
it to H. It is a digital input, and the range of L level input is 0 to 0.7(V) and
the range of H level input are 1.8 to 5.5(V). PWM can be input.
Pull-down resistance 100(kΩ) is built into in the terminal.
Motor drive control input pin.
Driving control input pin of OUT1 (10pin) and OUT2 (9pin). PWM can be
input. With built-in pull-down resistance.
Motor drive control input pin.
Driving control input pin of OUT3 (8pin) and OUT4 (7pin). PWM can be
input. With built-in pull-down resistance.
