Abstract

The invention discloses an NFC (near field communication) mobile terminal, which comprises an NFC chip, a button and a monostable trigger circuit, wherein the NFC chip is used for realizing an NFC function of the mobile terminal, the button is used for receiving the command of the user, the monostable trigger circuit is used for accepting the control of the button and making the NFC chip start the NFC function when delay signal is generated. The button is connected with the NC chip through the monostable trigger circuit and is used for starting the NFC function of the NFC mobile terminal when the NFC mobile terminal is powered off. According to the NFC mobile terminal, the NFC function of the NFC mobile terminal can be started through the button when the NFC mobile terminal is powered off, the NFC function is shut down when the NFC mobile terminal is powered off, the NFC chip is ensured to be active when in need and to be absolute shutting off when in non-communication state, and thus, the power consumption of the NFC chip is reduced when the mobile terminal is powered off.

Description

technical field [0001] The present invention relates to a mobile terminal, in particular to an NFC mobile terminal. Background technique [0002] Commonly used NFC (Near Field Communication, short-range wireless communication technology) chips all have an Enable signal, but in order to ensure that the chip still works when the chip is turned off, this signal is often pulled high by default during design. Therefore, for mobile phones with NFC function, the NFC function still maintains the working state when the mobile phone is turned off. , the leakage current of the whole machine is less than 0.1mA). In some unknown situations, after the NFC chip is accidentally activated, it may maintain a power consumption of 2mA or more, resulting in unnecessary power consumption. Contents of the invention [0003] In view of the shortcomings of the above-mentioned prior art, the purpose of the present invention is to provide an NFC mobile terminal, which can turn off the NFC chip of ...
