When the output load exceeds the current-limit threshold or a short is present, the device
limits the output current to a safe level by switching into a constant-current mode. When
continuous heavy overloads and short circuits increase the power dissipation in the switch,
causing the junction temperature to rise, a thermal protection circuit shuts the switch off to
prevent damage. Recovery from a thermal shutdown is automatic once the device has cooled
sufficiently. Internal circuitry ensures the switch remains off until a valid input voltage is
present.
