Claim:
1. 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: wherein the safety processor is configured to receive energy from a power source coupled to the power segment and perform a safety processor self-error check, 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 sequentially energizes 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.
