Abstract
The high-side switch circuit includes a first output MOS transistor that is connected, at a first end thereof, to a power supply terminal. The high-side switch circuit includes a second output MOS transistor that is connected to a second end of the first output MOS transistor at a first end thereof and to a voltage output terminal at a second end thereof. The high-side switch circuit includes a current detecting circuit that detects a current flowing through the first output MOS transistor and outputs a detection signal. The high-side switch circuit includes a first gate driver that applies a first control voltage to a gate of the first output MOS transistor. The high-side switch circuit includes a second gate driver that applies a second control voltage to a gate of the second output MOS transistor.
