Abstract: Embodiments of the present invention provide a voltage protection apparatus (130, 160, 205, 630, 730), comprising an input (165, 210, 610, 710) to receive an input voltage provided to a processor (120), an output (190, 260, 680, 760) to output a throttle signal to the processor (120), a filter circuit (180, 240, 640, 660, 740) to filter the input voltage provided to the processor (120) to provide a filtered input voltage, and a first circuit (170, 230, 630, 650, 73) to compare the filtered input voltage to a first threshold voltage (175, 235, 635, 645, 735) and to cause the output (190, 260, 680, 760) to provide the throttle signal to the processor (120) indicative of the filtered input voltage dropping below the first threshold voltage.

Abstract: Described is an apparatus and method to prevent a processor from abruptly shutting down by proactive power management. The apparatus comprises a power supply rail to receive a current and a voltage from a power supply generator (e.g., a DC-DC converter, and low dropout regulator); a processor coupled to the power supply rail, wherein the processor is to operate with a current and a voltage provided by the power supply rail; and an interface to receive a request to throttle one or more performance parameters of the processor when a monitored current through the power supply rail or a monitored voltage on the power supply rail crosses a threshold current or a threshold voltage, respectively, wherein the threshold current is below a catastrophic threshold current of a voltage regulator, or wherein the threshold voltage is above a catastrophic threshold voltage of the processor.
