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.
