Claim 18:
19. A method comprising:
supplying power from a power management circuit to a power-managed load integrated onto an integrated circuit;
detecting, by an undervoltage detect circuit, undervoltage events at the power-managed load;
detecting, by a current monitor circuit, a current that exceeds a specified threshold;
applying, by ones of a plurality of state machines in a control circuit, a plurality of different power management mechanisms to the power-managed load by a plurality of circuits, wherein at least a first circuit of the plurality of circuits is integrated onto the integrated circuit, and wherein at least a second circuit of the plurality of circuits is external to the integrated circuit; and
coordinating, by the ones of the plurality of state machines, the plurality of different power management mechanisms implemented by the plurality of circuits in a control circuit, wherein the coordinating includes using first and second state machines of the plurality of state machines to coordinate compensation mechanisms triggered by the undervoltage detect circuit and the current monitor circuit, respectively, wherein the undervoltage detect circuit and the current monitor circuit are responding to a same operational change of the power managed load.
