CHARGE CONTROL CIRCUIT, CHARGE CONTROL METHOD AND ASSOCIATED POWER MANAGEMENT INTEGRATED CIRCUIT

摘要

A charge control circuit includes an analog to digital converter (ADC) and a control unit, wherein the ADC is arranged for monitoring a temperature of a battery and converting the monitored temperature to a digital value; and the control unit is coupled to the analog to digital converter, and is arranged for determining whether to generate a control signal to adjust a charge current or a charging voltage of a battery or not according to the digital value, and the ADC and the control unit are fully hardware architectures.
