Abstract
Disclosed herein is a switch device including a switch element coupled between a power supply terminal and an output terminal, and an output abnormality detection circuit that. When an output current flowing during a turn-on period of the switch element is smaller than a threshold value, the output abnormality detection circuit detects an occurrence of an output abnormal condition, and increases a turn-on resistance of the switch element to determine which of a load-open condition and a short-to-power-supply-voltage condition is occurring at the output terminal on a basis of an output voltage at the output terminal.
