Abstract: The present invention provides a power circuit, including a current-limiting chip, a current-limiting value setting circuit, and a baseband chip. A current setting port of the current-limiting chip is connected to a general-purpose input/output port of the baseband chip through the current-limiting value setting circuit. The general-purpose input/output port is configured to generate a first signal in a first time sequence period of timeslot transmitting of the baseband chip so that the current-limiting value setting circuit sets a current-limiting value of the current-limiting chip as a first current-limiting value. In the other time sequence periods of timeslot transmitting of the baseband chip, the general-purpose input/output port generates a second signal so that the current-limiting value setting circuit sets the current-limiting value of the current-limiting chip as a second current-limiting value. The first current-limiting value is greater than the second current-limiting value.
