Equivalent Circuit

1

VCC

Power-supply voltage pin.

VCC 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).

2

ENA

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(k

Ω) is built into in the terminal.

3

IN1

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.

4

IN2

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.

6

GND

Ground pin.

7

OUT4

Driving output pin.

The motor coil is connected between terminal OUT3 (8pin).

8

OUT3

Driving output pin.

The motor coil is connected between terminal OUT4 (7pin).

9

OUT2

Driving output pin.

The motor coil is connected between terminal OUT1 (10pin).

10

OUT1

Driving output pin.

The motor coil is connected between terminal OUT2 (9pin).
