Abstract
There is provided a semiconductor switch apparatus that can handle a wide range of input voltages. The switch apparatus includes a main switch that is provided between a first terminal and a second terminal, and a switch controller that, to turn on the main switch, supplies the same gate-source voltage to the main switch irrespective of a direction of a current flowing through the main switch. To turn on the main switch, the switch controller supplies the gate-source voltage that is determined based on at least one of a voltage of the first terminal and a voltage of the second terminal to a gate of the main switch.
