CPC classification number: H03K17/56

Abstract: The switch device includes a first circuit. The first circuit has a first end coupled between a first terminal and a second terminal, and the first circuit has the second end coupled between the first terminal and the second terminal or coupled to a third terminal. The first circuit includes a first switch and a second switch. The first switch is coupled between the first end and the second end of the first circuit and is turned on or off according to a first control signal. The second switch is connected to the first switch in parallel and is turned on or off according to a second control signal. The first switch and the second switch include transistors of the same type. In a surge protection mode, the second switch is turned on to dissipate the surge current.
