Claim 11:
12. A method comprising:
receiving, at an integrated circuit, a plurality of supply voltages from a plurality of voltage regulators, wherein a plurality of power delivery trigger circuits is coupled to the integrated circuit and the plurality of voltage regulators, wherein the plurality of power delivery trigger circuits includes a first type of power delivery trigger circuit and a second type of power delivery trigger circuit coupled to one or more sets of voltage regulators in the plurality of voltage regulators, and wherein a given set of voltage regulators is coupled to at least one power delivery trigger circuit of the first type and at least one power delivery circuit of the second type;
generating, by the first type of power delivery trigger circuits coupled to the integrated circuit by a plurality of one-way wired interfaces, trigger signals when an electrical load experienced by the voltage regulators satisfies a first threshold; and
generating, by the second type of power delivery trigger circuits coupled to the integrated circuit by a plurality of two-way serial communication interfaces, trigger signals when the electrical load experienced by the voltage regulators satisfies a second threshold, wherein the first threshold is closer to a functional failure point of the integrated circuit than the second threshold.
