Abstract: A power control device can generate control signals to control operation of power sources. Additional control signals control operation of load switches that can be connected to the power sources to provide secondary sources of power. The load switches can be turned in a gradual manner at rates that depend on the power sources to which they are connected. The outputs of the load switches can be monitored for overvoltage and undervoltage conditions relative to the power sources to which they are connected.
Abstract translation: 功率控制装置可以产生控制信号以控制电源的操作。 附加的控制信号控制可连接到电源的负载开关的操作，以提供二次电源。 负载开关可以以依赖于它们连接的电源的速率逐渐地转动。 负载开关的输出可以相对于与它们连接的电源进行过压和欠压条件的监控。

Abstract: A charging circuit using a switch mode power supply to charge a battery from a connected external power adapter may periodically turn off the switch mode power supply and disconnect its input terminal from the switch mode power supply. A load may be connected to the input terminal. The input terminal is monitored for voltage collapse, indicating whether or not the power adapter is connected.
