1. A channel circuit comprising a power channel switch, a signal channel switch, a control module, and a comparison module, wherein
the power channel switch is connected between a circuit input end and a first circuit output end, and the signal channel switch is connected between the circuit input end and a second circuit output end;
the comparison module is connected to the circuit input end and is configured to compare an input voltage with a specified voltage threshold and feedback corresponding comparison results to the control module, wherein the specified voltage threshold comprises a first voltage threshold; and
the control module is configured to control the signal channel switch to be turned on and the power channel switch to be turned off when the input voltage is lower than the first voltage threshold, and to control the signal channel switch to be turned off when the input voltage is higher than the first voltage threshold, wherein the comparison module comprises a second comparison unit configured to compare the input voltage with the second voltage threshold in the specified voltage threshold, and the second comparison unit is connected between the circuit input end and the control module.
