  • Publication number: 20110285344
    Abstract: A charge device includes a charge unit and a voltage detecting circuit. In an operation mode, the charge unit adjusts an output current according to an input voltage to charge a rechargeable device. The voltage detecting circuit generates a feedback voltage according to the value of the output current. In addition, the charge unit further determines an output voltage across the rechargeable device according to the feedback voltage and reduces the output current when the output voltage is less than a first predetermined voltage.
