Pin Function

VCC

Power supply pin for output and controller.

GND

GND pins for output and controller. Both

must be grounded.

IN2

IN1

IN3

IN4

Input pins that determine the excitation of

the outputs.

IN1 and IN2 control outputs OUT1 and

OUT2; IN3 and IN4 control outputs OUT3

and OUT4.

When inputs IN1 through IN4 are all low or

open, the device goes into standby mode

and current consumption drops to 10 µA or

less.

L: –0.3 to +0.7 V

H: 3.0 to 9.0 V

There are no limitations on the magnitude

relationships between the VCC and VIN

supply voltages.

OUT4

OUT3

OUT1

OUT2

Output pins.

Have built-in spark killer diodes. Braking

provides short braking that turns on the

lower transistor.

Vref

Reference voltage (= 2.0 V).

VC1

VC2

Output

Input pins that determine the constant-

voltage regulated output level.

The constant-voltage regulated output VO

(= voltage between H side output and

GND) is controlled by VO =2.5xVC. There

are no limitations on the magnitude

relationships between the VCC,VC1 and

VC2 supply voltages.
