The constant-voltage regulated output VO (= voltage between H side output and GND) is controlled by VO = 2.5 × VC. The output

is in the saturated state when the VC input range is 0.2 to 6 V and VO ^ VCC.

Pin Function

VCC

Power supply pin for output and controller.

GND

GND pins for output and controller.

Both must be grounded.

IN2

IN1

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 or open

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.

Vref

Reference voltage (= 2.0 V).
