DRAIN

Source (ground) pins.

Input pin.

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

open-circuited, the output never turns on inadvertently.

Drain pins.

The output current is limited to 5 A (typ.) even if an excessive current flows into a device due to an

in-rush current of a lamp or load short-circuit.
