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 pin.
When a load short-circuit causes an overcurrent (8 A min) to flow into a device, the output
automatically turns on and off repeatedly.
