摘要： To reduce errors and decrease loss, the detecting range of current is enlarged and the current is independently detectable. A rectified voltage and a rectified current are supplied from an input terminal. Resistors 1 and 2 are serially connected between the input and output terminals. A load is connected to the output terminal. Between an emitter and collector of the transistor are resistor 1 and a constant current detecting circuit 5. The transistor base is connected to a control circuit that controls the transistor switching operations. The constant current detecting circuit 5 detects current from the voltage across resistor 1. A current detecting circuit 6 detects current from the voltage across resistor 2. A signal is supplied to the control circuit when the constant current detecting circuit 5 detects small current. The control circuit supplies a signal to the transistor base that increases transistor impedance.

摘要： The present invention provides a highly safe charging circuit with which overcharge of a secondary battery will never occur even when a failure occurs in a transistor or the like that controls the charging voltage or charging current or when a protection circuit does not operate normally. In a secondary battery charging circuit 4 that charges a secondary battery E2 with an input power source voltage, the power source voltage is set to a voltage (e.g. 4.0 V) that is lower than the full-charge voltage (e.g. 4.2 V) of the secondary battery. When the voltage of the secondary battery E2 is lower than the power source voltage, a constant current circuit operates to perform constant current charging without voltage step-up, and when the voltage of the secondary battery E2 is higher than the power source voltage and lower than the full-charge voltage, a voltage step-up circuit operates to perform constant current charging with voltage step-up.
