Abstract
In a semiconductor switch, a resistance value between a current input terminal to which a current is input and a current output terminal from which a current is output decreases as a voltage of a control terminal based on a potential of the current output terminal increases. A booster circuit is disposed on a path extending from the current input terminal to the control terminal. The booster circuit boosts a voltage input from the current input terminal side and applies the boosted voltage to the control terminal. A switch is connected between the control terminal and the current output terminal of the semiconductor switch. The switch is switched off by power consumption. The power consumption stops and the switch switches on if the supply of power to the booster circuit stops.
