Abstract
A switch device includes: a power supply terminal; an output terminal; a switch element configured to be connected between the above terminals; a signal output terminal configured to output an output current detection signal corresponding to an output current that flows during the on period of the switch element; an overcurrent protection circuit configured to restrict the output current detection signal to an overcurrent restriction value or less during the on period of the switch element; and an output abnormality detection circuit configured to monitor, while switching between a first state where no current is supplied to the output terminal and a second state where a current is supplied to the output terminal during the off period of the switch element, the output voltage of the output terminal in each of the first and second states, and to switch the logic level of the output current detection signal.
