Claim 10:
11. A system comprising:
an integrated circuit comprising a power-managed load;
a power management circuit coupled to the integrated circuit and configured to supply power to the power-managed load;
an undervoltage detect circuit configured to detect undervoltage events at the power-managed load;
a current monitor circuit configured to detect current to the power-managed load that exceeds a specified threshold;
a plurality of circuits wherein:
respective circuits of the plurality of circuits implement different power management mechanisms,
the different power management mechanisms affect the power-managed load,
at least a first circuit of the plurality of circuits is integrated onto the integrated circuit, and
at least a second circuit of the plurality of circuits is external to the integrated circuit; and

a control circuit coupled to the plurality of circuits and configured to coordinate power management mechanisms implemented by the plurality of circuits, wherein the control circuit includes a plurality of state machines associated with corresponding ones of the power management mechanisms, wherein the control circuit is configured to, using first and second ones of the plurality of state machines, respectively, coordinate a compensation mechanism triggered by the undervoltage detect circuit with a compensation mechanism triggered by the current monitor circuit, wherein the undervoltage detect circuit and the current monitor circuit are responding to a same operational change of the power-managed load.
