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.
