More Information
Summary:A disclosed current detection circuit includes a current/voltage converting element for generating a voltage in accordance with an input current, a reference voltage generation circuit for generating a reference voltage, the reference voltage generation circuit having an element configuration for setting a predetermined temperature characteristic to the reference voltage, and a comparator for outputting an output signal in accordance with a magnitude relation between a voltage converted in the current/voltage converting element and the reference voltage generated in the reference voltage generation circuit.
