Power management through segmented circuit and variable voltage protection

A surgical instrument control circuit, comprising:

• a primary processor;
• a safety processor;
• and
• a segmented circuit comprising a plurality of circuit segments in signal communication with the primary processor, the plurality of circuit segments comprising:
• a power segment configured to provide a segment voltage to the primary processor, the safety processor, and each of the plurality of circuit segments, the power segment comprising a boost convertor,
• wherein the safety processor is configured to receive energy from the boost convertor and perform a safety processor self-error check when a power source is connected to the power segment,
• wherein the safety processor is further configured to energize the primary processor when no errors are detected during the safety processor self-error check,
• wherein when the primary processor is energized the primary processor is configured to perform a primary processor self-error check, and wherein when no errors are detected during the primary processor self-error check the primary processor is configured to sequentially energize each of the plurality of circuit segments to prevent a large current draw from the plurality of circuit segments being turned on simultaneously in an uncontrolled manner.
