    • The present invention discloses a charge control circuit for supplying power from an external power source to a first common node and charging a second common node from the first common node. A regulator circuit is coupled between the external power source and the first common node, and a transistor is coupled between the first common node and the second common node. The present invention detects an operation parameter of the transistor and controls an internal voltage source to generate a non-predetermined voltage difference accordingly. When the sum of the voltage at the second common node and the non-predetermined voltage is equal to or higher than the reference voltage, the voltage at the first common node is regulated to a level higher than the voltage at the second common node, and the transistor is in an optimum conductive state.
    • 本发明公开了一种用于从外部电源向第一公共节点提供电力并从第一公共节点对第二公共节点充电的充电控制电路。 调节器电路耦合在外部电源和第一公共节点之间,并且晶体管耦合在第一公共节点和第二公共节点之间。 本发明检测晶体管的操作参数,并且控制内部电压源以相应地产生非预定的电压差。 当第二公共节点和非预定电压之间的电压之和等于或高于参考电压时,第一公共节点处的电压被调节到高于第二公共节点处的电压的电平,以及 晶体管处于最佳导通状态。

    • A charger including a regulator, a controller and a compensation-adjusting unit for accurately charging to a battery device is provided. The regulator provides a charging current to the battery device. The controller is coupled to the regulator for controlling the charging current. The compensation-adjusting unit is coupled to the regulator and the battery device for receiving a first reference voltage. In a first operation mode, the compensation-adjusting unit outputs the first reference voltage to the regulator. In a second operation mode, the controller instructs the regulator to transiently generate a first charging current and a second charging current. Responsive to the first and the second charging currents, the output voltage of the battery device presents a first output voltage and a second output voltage. The compensation-adjusting unit pre-estimates a parasitic resistance of the battery device by detecting the first and the second output voltage, thus compensating the first reference voltage.
    • 提供一种包括调节器,控制器和用于对电池装置进行精确充电的补偿调节单元的充电器。 调节器向电池装置提供充电电流。 控制器耦合到调节器以控制充电电流。 补偿调节单元耦合到调节器和电池装置,用于接收第一参考电压。 在第一操作模式中,补偿调整单元将第一参考电压输出到调节器。 在第二操作模式中,控制器指示调节器暂时产生第一充电电流和第二充电电流。 响应于第一和第二充电电流,电池装置的输出电压呈现第一输出电压和第二输出电压。 补偿调整单元通过检测第一和第二输出电压来预测电池装置的寄生电阻,从而补偿第一参考电压。
