Abstract

See full text

A switch circuit includes a control unit, a driving unit, a voltage sudden-change unit, and a connection unit. The connection unit is configured to turn on or turn off an electrical connection between a power-supply device and a load. The control unit is configured to control the driving unit to output or stop outputting a driving signal to the connection unit, where the driving signal allows to turn on the connection unit. The voltage sudden-change unit is coupled with a driving node between the driving unit and the connection unit. The control unit is configured to control the voltage sudden-change unit to output a voltage sudden-change signal to the driving node, where the voltage sudden-change signal allows to make the connection unit be switched to a turned-off state from a turned-on state quickly when the driving unit stops outputting the driving signal.
