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: Disclosed is a battery charging circuit having several operating modes include boost and buck mode, and forward and reverse mode. A power train and a current sensing block may share power transistors thus reducing the number of space-consuming power devices in the circuit. The current sensing block may indicate output current based only a sensed input current, and vice versa.
Abstract translation: 公开了一种具有若干工作模式的电池充电电路，包括升压和降压模式以及正向和反向模式。 动力传动系和电流感测块可以共享功率晶体管，从而减少电路中耗费空间的功率器件的数量。 电流检测块可以仅基于感测的输入电流来指示输出电流，反之亦然。

Abstract: A power control device can generate control signals to control operation of power sources. At least one of the control signals may be referenced to an internally provided reference voltage or an externally provided reference voltage. 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.
