Patent ID: 7352159

Claim:
An information handling system comprising: plural processing components operable to process information; a power supply operable to supply DC voltage to operate the processing components; at least one regulator interfaced between the power supply and at least one processing component, the regulator operable to interface a capacitor with the processing component and the power supply to reduce an overvoltage event; a regulator controller interfaced with the regulator and operable to detect an overvoltage event, the regulator controller selectively interfacing the capacitor if an overvoltage event is detected; and a negative voltage protection MOSFET driver operating on the regulator controller and operable to detect a negative voltage event following the interfacing of the capacitor, the negative voltage protection MOSFET driver further operable to remove the interface with the capacitor for a first overvoltage condition and to continue the interface with the capacitor for a second overvoltage condition.
