Abstract
A control circuit configured to receive a control signal that defines a first phase and a second phase from a surgical generator. The control circuit may include a first resistor, a second resistor in parallel with the first resistor, and a switch in series with the second resistor. The switch may be configured to transition between an open state and a closed state corresponding to an operational mode of a surgical instrument. In the first phase of the control signal, the control circuit is configured to communicate surgical instrument information to the surgical generator. In the second phase of the control signal and in the open state of the switch, the control circuit is configured to provide a first output. In the second phase of the control signal and in the closed state of the switch, the control circuit is configured to provide a second output.
