Abstract
A current detection circuit includes: an input port; an output port; a rectifying element; a capacitor; a first first conductivity type MOS transistor; and a voltage detection circuit. The input port is connected to an anode terminal of the rectifying element, the drain terminal of the first first conductivity type MOS transistor, and a voltage detection terminal of the voltage detection circuit. A cathode terminal of the rectifying element is connected to a first terminal of the capacitor and a gate terminal of the first first conductivity type MOS transistor. A second terminal of the capacitor and a source terminal of the first first conductivity type MOS transistor are connected to a first power source terminal. A detection result output port of the voltage detection circuitis connected to the output port.
