DETAILED PIN DESCRIPTION

A capacitor connected to this pin is used to set the duration

the turn on delay. The delay starts after the UVLO threshold

has been reached.

This pin controls the state of the output NPN switch 1. A Logic

0 holds the switch off while a Logic 1 turns the switch on.

This pin controls the state of the output NPN switch 2. A Logic

0 holds the switch off while a Logic 1 turns the switch on.

This pin is the emitter of switch 1. This pin is connected to the

load in the High-Side switch configuration, and is connected

to Ground in the Low-Side configuration.

This pin is the emitter of switch 2. This pin is connected to the

load in the High-Side switch configuration, and is connected

to Ground in the Low-Side configuration.

This pin is the collector of switch 1. This pin is connected to the

to the load in the Low-Side configuration.

This pin is the collector of switch 2. This pin is connected to the

to the load in the Low-Side configuration.

FAULT

This pin is an open collector output that is pulled to Ground in

the event of a short circuit, an overcurrent, or a thermal shut

down.
