Abstract
A charger circuit comprises a constant current charging circuit and a thermal regulation circuit. The constant current charging circuit is configured for generating a charging current, including a charger input terminal for receiving an input voltage, a charge current setting terminal, a charger output terminal for outputting the charging current, a current mirror including a reference current path between the charger input terminal and charge current setting terminal and an output current path between the charger input terminal and charger output terminal, and a feedback amplifier having a positive terminal, a negative terminal for receiving a feedback reference voltage, and a feedback output terminal coupled to the current mirror. The thermal regulation circuit is configured for generating and modulating a thermal regulation voltage with temperature, and outputting the thermal regulation voltage across the positive terminal of the feedback amplifier and the charging current setting terminal.
