Patent attributes
An NFC interface with an energy management function. The NFC interface has an independent energy antenna, and the NFC interface comprises an energy management module and an energy storage module, wherein the energy management module is electrically connected to the energy storage module; and the energy management module is used for charging the energy storage module according to electric energy collected by the energy antenna, and is further used for cutting off charging to the energy storage module when the energy storage module pulls down a voltage collected by the energy antenna to a first voltage threshold value. By means of adding an energy management module to dynamically manage collected energy, the present invention can greatly improve the energy receiving power of an NFC interface, and also carries out storage management on the electric energy, thereby allowing an apparatus with such an NFC interface to collect more energy; and can output more NFC energy to the outside, so that the NFC interface has more extensive use.
