Abstract
A semiconductor device includes: a current sense circuit that generates a current sense signal corresponding to a monitoring target current; an error amplifier; a comparator; and a controller. The current sense circuit includes: a differential amplifier of a current output type; a first input resistor connected between a first input terminal of the differential amplifier and a first current sense terminal; a second input resistor connected between a second input terminal of the differential amplifier and a second current sense terminal; an output resistor configured to be connected to the output terminal of the differential amplifier; a first feedback current path across which a first feedback current is passed between the first input terminal and the output terminal of the differential amplifier; and a second feedback current path across which a second feedback current is passed between the second input terminal of the differential amplifier and the output terminal.
