Patent ID: 8271819

Claim:
An information handling system (IHS) provided with overcurrent protection comprising: a power supply operable to provide an output current to the IHS during power initiation, the power supply comprising overcurrent protection circuitry and a power supply control; a first power component associated with a first power stage having a first current threshold; and a power control logic coupled to the power supply and the first power component, wherein the power control logic is operable during power initiation to communicate the first power stage and the first current threshold to the power supply via a Power Management Bus (PMBus), and wherein if the output current does not exceed the first current threshold during the first power stage, the power control logic is operable to communicate a second power stage having a second current threshold to the power supply, wherein the power supply control communicates the first current threshold to the overcurrent protection circuitry, and wherein the overcurrent protection circuitry is operable to indicate an overcurrent to the power supply control if the output current exceeds the first current threshold during the first power stage or exceeds the second current threshold during the second power stage.
