Abstract
The present disclosure illustrates a battery charging circuit, adapted for charging a rechargeable battery. The battery charging circuit includes a temperature sensing unit, a current control unit, and a charging unit. The temperature sensing unit is coupled to a temperature output pin of the rechargeable battery to output a temperature signal according to the sensed temperature of the rechargeable battery. The current control unit is coupled to the temperature sensing unit for outputting a control voltage according to the received temperature signal. The charging unit is coupled to the current control unit and outputs a charging current to charge the rechargeable battery. When temperature of the rechargeable battery exceeds a predefined temperature range, the charging unit discontinues outputting the charging current. Hence, the battery charging circuit can completely fulfill the charging requirement of the rechargeable battery thereby increase the associated charging efficiency.
