Abstract
A current detection circuit can include: a detection power switch coupled to a power switch to be detected; a current control circuit configured to control voltages of power terminals of the detection power switch in order to generate a detection current flowing through the detection power switch when the power switch is on; and where a flowing direction of the detection current is consistent with a flowing direction of a current flowing through the power switch.
