Systems and methods for controlling a segmented circuit

A powered surgical instrument, comprising:

• an end effector configured to perform a plurality of end effector functions, wherein said end effector is configured to receive a staple cartridge comprising a plurality of staples removably stored therein;
• a knife;
• a DC motor configured to advance said knife within said end effector;
• a primary processor;
• a motor controller in signal communication with said primary processor, wherein said DC motor is electrically coupled to said primary processor through a plurality of H-bridge drivers and said motor controller, and wherein said primary processor provides data to said motor controller;
• a control circuit, comprising:
• a power assembly configured to provide a source voltage;
• and
• a voltage boost convertor coupled to said power assembly, said voltage boost convertor configured to provide a set voltage greater than said source voltage;
• and
• a power source configured to provide power to said DC motor and one or more components of said powered surgical instrument, wherein said primary processor decreases power to the one or more components of said powered surgical instrument based on said DC motor being actuated.
