Abstract
The present disclosure provides a current detection circuit having a high detection precision. The current detection circuit includes: a current output type differential amplifier; a first input resistor, configured to be connected between a first input end of the differential amplifier and a first current sense terminal; a second input resistor, configured to be connected between a second input end of the differential amplifier and a second current sense terminal; an output resistor, configured to be connected to an output end of the differential amplifier; a first feedback current path, configured to allow a first feedback current to flow between the first input end and the output end of the differential amplifier; and a second feedback current path, configured to allow a second feedback current to flow between the second current sense terminal and the output end of the differential amplifier.
