Abstract
A plurality of current control MOS transistors and a plurality of current detection systems are provided, each of the current detection systems including a current detection transistor current-mirror connected to the current control MOS transistor and a current-voltage converter connected in series to the current detection transistor. The current detection systems are switched between one another for operation in response to the intensity of a charging current flowing through the current control transistors.
