发明名称 Systems and methods for charging a battery with a digital charge reduction loop
摘要 Exemplary systems and methods for charging a battery with a digital charge reduction loop are described herein. In some embodiments, a system comprises an exemplary digital charge reduction loop which comprises a circuit for determining a charge-current adjustment signal, a counter for generating a digital count value, and a digital-to-analog converter. The circuit for determining a charge-current adjustment signal may base the determination on a source voltage of an input source. The counter may generate a digital count value based on the charge-current adjustment signal. The digital-to-analog converter (DAC) may generate a DAC control signal based on the digital count value of the counter, the DAC control signal being representative of an amount of charge current to be used to charge a battery.
