Abstract

A charging apparatus is provided. A detection circuit includes a voltage dividing path between an output terminal of a charging circuit and an output terminal of a reference voltage generating circuit. The detection circuit provides a detection signal according to a divided voltage on the voltage dividing path. A control circuit determines whether a load is connected to the charging apparatus according to the detection signal.
