摘要： In one implementation, an input power management component receives an input power, and determines whether an input current and voltage satisfies predetermined thresholds. A boost component generates a boost output voltage using the input voltage if the input current satisfies a predetermined current threshold, and a step-down charging component converts the boost output voltage to a voltage for charging a battery and system power management.

摘要翻译： 在一个实现中，输入功率管理组件接收输入功率，并且确定输入电流和电压是否满足预定阈值。 如果输入电流满足预定电流阈值，则升压组件使用输入电压产生升压输出电压，降压充电部件将升压输出电压转换成用于对电池充电的电压和系统电源管理。

摘要： Methods of and apparatus for controlling power drawn by an appliance through a USB port. The method includes limiting any electrical current drawn by an appliance to one of seven levels according to whether the data lines receive a bias from a power line, the data lines are in electrical communication with each other, and the power source includes a host computing device, or according to logic and voltage levels of the data lines when any of the pull-down resistor and the current and voltage sources are connected or not connected to the D+ data line. The apparatus includes a controller programmed to selectively connect a pull-down resistor, a current source, and a voltage source to a D+ data line and to limit any electrical current drawn from a power source to one of the seven levels according to voltage levels on the D+ data line and a D− data line.
