When the electronic device 10 is powered on and working normally, the NFC chip 111 can trigger the wake-up of the application processor 120 through the wake-up 2 port. This is the normal working mode. That is to say, by reusing the wake-up end of the NFC chip 111 to wake up the 2 port, the port signal line is simultaneously connected to the general IO (Input/Output) port of the application processor 120 and the GPIO (General-Open) of the normally open co-processor 141.

The NFC signal controls the first switch 142 to be turned on; when the first switch 142 is in the on state, the power management chip 130 supplies power to the application processor 120 to turn on the electronic device 10 .

It can be understood that, as shown in FIG. 3 , the power-on signal line of the power management chip 130 is at a high level when the electronic device 10 is in a shutdown state, for example, it can be 1.8V or 1.2V. This power-on signal line normally operates at a high level. When the power button 160 is held low for a period of time, the power management chip 130 determines that the user needs to power on by long-pressing the power button 160 . Based on this principle, in this embodiment, as shown in Figure 3, an NMOS tube is added. The drain of the NMOS tube is connected to the startup signal line of the power management chip 130, that is, the second end of the power management chip 130.

In one embodiment, according to Figure 2 and Figure 3, it can be seen that if it needs to be turned on without unpacking, the NFC chip 111 needs to maintain power supply in the shutdown state. In future application trends, there may be some areas such as export abroad. In the case of long-term transportation and storage, the "transport mode" needs to be enabled when the electronic device 10 leaves the factory. When the electronic device 10 is in the transportation mode and is turned off, only the power management chip 130 is powered, and other modules are not powered.

In order to start the electronic device 10 in the transportation mode, in this embodiment, as shown in FIG. 4 , the driving circuit 140 includes a first filter unit 143 and a second switch 144 . One end is connected to the NFC antenna 113, the second end of the first filter unit 143 is connected to the control end of the second switch 144, the first end of the second switch 144 is connected to the second end of the power management chip 130, the second switch 144 The second terminal is grounded.

The signal is used to drive the NMOS transistor to conduct, to pull the boot signal line low, to drive the power management chip 130 to supply power to the application processor 120, to start the electronic device 10 .

It can be understood that in this embodiment, when it is necessary to trigger the electronic device 10 in the packaging box to turn on, the NFC device can be used to perform radio frequency field emission on the electronic device 10 in the packaging box, so that the NFC of the electronic device inside the packaging box The antenna obtains energy and can "press" the power button.

It can be understood that in this embodiment, the field intensity emission time of the NFC device is approximately equal to the time when the power button of the mobile phone electronic device 10 is pressed. The emission time can be determined according to specific rules as needed to achieve different communication effects. For example, a single long-term transmission, such as continuous transmission for 10 seconds, is equivalent to pressing the power-on button of the electronic device 10 for 10 seconds, and the power management chip 130 determines that the power is turned on. For another example, the transmission time can be changed periodically to achieve one-way data transmission, such as transmitting for 1 second, stopping for 1 second, and cycling 5 times to indicate booting for OTA (Over the Air Technology) software upgrade.

Coprocessor 141 and NFC chip 111 are powered to enable electronic device 10 to exit transport mode.

In a specific example, when the electronic device 10 is in the transportation mode and is turned off, only the power management chip 130 is powered, and other modules are not powered, that is, the application processor 120, the normally-on co-processor 141 and the NFC chips 111 are not powered. Then, when the electronic device 10 is in the transportation mode and is in the power-off state, the NFC device sends the second NFC signal. The NFC antenna 113 receives the second NFC signal to generate a second voltage signal, and rectifies the second voltage signal into a DC signal, the second target, through a low-pass filter composed of a diode 1721, a resistor 1722, and a capacitor 1723, that is, the second filtering unit 172. signal to drive the NMOS transistor to conduct, thereby pulling down the boot signal line. The electronic device 10 exits the transportation mode, that is, the power management chip 130 supplies power to the normally open coprocessor 141 and the NFC chip 111. At this time, the normally open coprocessor 141 In low power sleep mode.

In a specific example, after the NFC chip 111 is powered on, the NFC device sends a first NFC signal, where the first NFC signal may carry a power-on instruction. The NFC antenna 113 receives the first NFC signal and sends the first NFC signal to the NFC chip 111 through the antenna matching unit 112 . After receiving the first NFC signal, the NFC chip 111 detects that the first NFC signal carries a power-on command, and wakes up the AOSP through its wake-up end, namely the wake-up 2 port. The AOSP notifies it through the communication link with the power management chip 130 The application processor 130 supplies power to enable the electronic device to be powered on.

In one embodiment, when the electronic device 10 is in a powered-on state, the application processor 120 performs the setting operation; when the setting operation is completed or the power-on time of the electronic device 10 exceeds the set time threshold, The electronic device 10 re-enters the shutdown state.

The above setting operations include, but are not limited to, software OTA system emergency upgrade services, personalization Start-up candidate language function and personalized startup page function.
