    • In accordance with the teachings described herein, a method and apparatus for handling a charging state in a mobile device is provided. A universal serial bus (USB) interface may be used for connecting the mobile device to a USB host. A processing device may be used to execute programs and to control operation of the mobile device, the processing device may be further operable to receive an enumeration acknowledgement signal from the USB host via the USB interface. A rechargeable battery may be used for powering the processing device. A voltage regulator may be coupled to the USB interface and operable to receive a USB bus voltage from the USB interface and use the USB bus voltage to power the processing device. A timing circuitry may be used to disable the voltage regulator from powering the processing device after a pre-determined amount of time has expired, the timing circuitry being operable to measure the passage of the pre-determined amount of time upon detecting the USB bus voltage. A battery charger may be used to receive the USB bus voltage from the USB interface and use the USB bus voltage to power the processing device and to charge the rechargeable battery. The processing device may enable the battery charger to power the processing device and to charge the rechargeable battery when the enumeration acknowledgement signal is received from the USB host.
    • 根据本文所述的教导,提供了一种用于在移动设备中处理充电状态的方法和装置。 通用串行总线(USB)接口可用于将移动设备连接到USB主机。 处理设备可以用于执行程序并控制移动设备的操作,处理设备还可以用于经由USB接口从USB主机接收枚举确认信号。 可以使用可充电电池为处理装置供电。 电压调节器可以耦合到USB接口并且可操作以从USB接口接收USB总线电压,并且使用USB总线电压为处理设备供电。 可以使用定时电路来在预定量的时间期满之后禁止电压调节器对处理装置供电,定时电路可操作以在检测到USB总线电压时测量预定时间量的通过 。 可以使用电池充电器从USB接口接收USB总线电压,并使用USB总线电压为处理设备供电并为可充电电池充电。 当从USB主机接收到枚举确认信号时,处理装置可以使得电池充电器为处理装置供电并对可再充电电池充电。
