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.
