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

摘要

PROBLEM TO BE SOLVED: To provide a charge control circuit, a charge control method and an associated power supply management integrated circuit.SOLUTION: The charge control circuit includes an analog/digital converter (ADC) and a control unit. The ADC is provided for monitoring a temperature of a battery and converting the monitored temperature into a digital value. The control unit is coupled to the analog/digital converter and provided for determining whether to generate a control signal for regulating a charge current or a charge voltage of the battery in accordance with the digital value. The ADC and the control unit have perfect hardware configurations.SELECTED DRAWING: Figure 2
