Pin Description

1

SOURCE1

Source pin 1

2

IN1

Input pin 1

This pin is connected to a pull-down resistor internally, so that even when input wiring is

open-circuited, output can never be turned on inadvertently.

3

SOURCE2

Source pin 2

4

IN2

Input pin 2

This pin is connected to a pull-down resistor internally, so that even when input wiring is

open-circuited, output can never be turned on inadvertently.

5, 6

DRAIN2

Drain pin 2

Drain current is limited (by current limiter) if it exceeds 3 A (min) in order to protect the IC.

7, 8

DRAIN1

Drain pin 1

Drain current is limited (by current limiter) if it exceeds 3 A (min) in order to protect the IC.
