Abstract
The embodiments provide a mobile hotspot UFI device and a start-up method. The UFI device includes a battery, a main control chip, a power management chip and a start-up control unit. The power management chip internally provides a control signal at a first electric potential, and when the control signal is at a second electric potential, the power management chip controls the battery to supply electricity to hardware of the UFI device. When the main control chip does not output a GPIO signal, the start-up control unit conducts the external power supply to the control signal, so as to make the control signal change from the first electric potential to the second electric potential. When the main control chip outputs the GPIO signal, the start-up control unit disconnects the external power supply from the control signal.
