Abstract

A powered surgical instrument is disclosed comprising a motor, a shaft extending from the housing, an end effector extending from the shaft, a power source, a processor, a motor controller, and a control circuit. The control circuit comprises a first segment configured to supply the processor with a first voltage from the power source, and a second segment configured to supply the motor controller with a second voltage from the power source. The second voltage is different than the first voltage. The powered surgical instrument further comprises means for shifting power to the first segment when the second segment experiences a power drop due to high power demand from the motor.

Claims
