Abstract
Disclosed is a current detection circuit including: a current-to-voltage converter; a comparator including one input terminal to which a voltage that is current-to-voltage converted is input and the other input terminal to which a voltage as a reference for comparison or a voltage converted from the current to be detected is input; and a hysteresis circuit. The hysteresis circuit includes: a current source circuit; and a switch connected in series with the current source circuit, and the switch is switched to an on state or an off state by output of the comparator, thereby a current flowed in the current-to-voltage converter is increased or decreased by the current of the current source circuit, and the voltage converted from the current to be detected or from the reference current changes and thereby the hysteresis circuit provides hysteresis to the comparison operation of the comparator.
