Patent ID: 8742820

Claim:
A power circuit, comprising: a current-limiting value setting circuit; a baseband chip; a current-limiting chip, wherein 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, wherein 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; and generate a second signal in other time sequence periods of timeslot transmitting of the baseband chip so that the current-limiting value setting circuit sets the current-limiting value of the current-limiting chip as a second current-limiting value, wherein the first current-limiting value is greater than the second current-limiting value.
