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.
