Abstract
It is an object of the present disclosure to reduce the number of constituent components and accurately detect a current. A current detection circuit detects a current flowing through a DC/DC converter. A first output unit applies, to a third signal path, a voltage that corresponds to an output from a detection sensor, which has detected a larger current, out of a first sensor and a second sensor. Furthermore, the first output unit applies, to the third signal path, a voltage obtained by reflecting a voltage drop at the transistor or the transistor that is connected to the detection sensor, in the voltage output from the detection sensor. A second output unit applies, to a fourth signal path, a voltage obtained by reflecting a voltage drop that occurs between a base and an emitter of a transistor, in the voltage applied to the third signal path.
