Equivalent Circuit Diagram

Pin Function

Power supply pin for output and controller.

GND pins for output and controller. Both

must be grounded.

Input pins that determine the excitation of

the outputs.

IN1 control outputs OUT1 and OUT2; IN2

control outputs OUT3 and OUT4.

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.

Output pins.

Have built-in spark killer diodes.

Reference voltage (= 2.0 V).

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 = 2.5 x VC. There

are no limitations on the magnitude

relationships between the VCC and VC

supply voltages.

Standby/drive control input pin

Current consumption in standby mode is

10 µA or less.

L: –0.3 to + 0.7 V

H: 3.0 to 9.0 V

Output

Output voltage setting

Control input pin for switching between

constant voltage output and saturated

output. There are no limitations on the

magnitude relationships between the VCC,

VM1 and VM2 supply voltages.

L: –0.3 to + 0.7 V

(constant-voltage regulated output)

H: 3.0 to 9.0 V (saturated output)
