ABSTRACT:
In a charging circuit, a current correcting circuit is provided which includes a transistor, the collector current of which is permitted to flow through a resistor for setting up a reference voltage for a comparator circuit. The current correcting circuit is arranged such that when the output voltage of the charger goes below a predetermined level, the transistor is rendered conductive to compensate for the decrease in the reference current, thereby preventing the current from being decreased which flows through the resistor of the comparator circuit.
