The electronic tag chip 33 can also support the realization of Type-C finished product head or finished product cable system programming through CC pins. The electronic tag chip 33 identifies each other through the internal programming code (ID) and the programming code in the PD adapter 2, or, the electronic tag chip 33 announces the ID (i.e., the programming code) of the Type-C charging wire 1 to the PD adapter 2 through the CC pin, and after the IDs are matched with each other, the PD spoofer 32 can only assign the output voltage level.
The PD spoofer 32 is a USB PD sink controller, also referred to as a PD powered end chip or a PD spoofing chip, and the PD spoofer 32 uses the HUSB238, and the rated power of the transmission can reach 100W. HUSB238 is PD 3.0V 1.3 and Type-C V1.4 compatible. It can also support BC1.2 DCP, CDP and SDP and apple5v2.4a charging protocols.

The high-power charging output refers to charging output with the power of 65W-240W, even more than 240W, wherein the voltage is 9-48V, and the current is 5-12A; the non-high power is a power of 65W or less.
The electronic tag chip 33, the PD decoy 32 and the MCU chip 34 are all arranged on the PCB 31, the PCB 31 is arranged in the Type-C plug 12 of the Type-C charging wire 1, the PCB 31 is further connected with the connecting wire 11, and the other end of the connecting wire 11 is connected with the non-quick-charging physical interface 13.
The negative electrode of the non-fast-charging physical interface 13 is connected to the protection switch 36 and then to the ground, the negative electrode of the non-fast-charging physical interface 13 is connected to the VBUS end of the Type-C plug 12, the MCU chip 34 is connected to the electronic switch to control the protection switch 36 to be turned on, the MCU chip 34 is connected to the output voltage detection circuit 37, the output voltage detection circuit 37 is connected to the VBUS end and detects the VBUS end voltage, the MCU chip 34 determines whether the VBUS end actual voltage detected in the charging process is consistent with the output voltage specified by the PD spoofer 32, when the VBUS end actual voltage is consistent with the specified output voltage, the MCU chip 34 controls the protection switch 36 to be turned on to realize charging, when the VBUS end actual voltage is inconsistent, the MCU chip 34 controls the protection switch 36 to be turned off to not charge, in addition, the MCU chip 34 also timely controls the protection switch 36 to be turned off to cut off a charging loop to achieve the purpose of the protection device 100, and thus the protection mechanism is enabled to be safer and more reliable to use.
More specifically, the protection switch 36 is a MOS transistor, the G pole of the MOS transistor is connected to the MCU chip 34, the D pole of the MOS transistor is connected to the negative pole of the non-fast-charging physical interface 13, and the S pole of the MOS transistor is connected to the ground. When the MOS tube is conducted, the negative electrode of the non-quick-charging physical interface 13 is grounded, so that a charging loop is realized, and the circuit is simpler and the cost is lower because the protection switch 36 is one MOS tube.
Or, a protection switch 36 is connected between the positive pole of the non-fast-charging physical interface 13 and the VBUS end, the negative pole of the non-fast-charging physical interface 13 is grounded, the MCU chip 34 is connected to the protection switch 36 to control the protection switch 36 to be turned on, the MCU chip 34 is connected to an output voltage detection circuit 37, the output voltage detection circuit 37 is connected to the VBUS end and detects the VBUS end voltage, the MCU chip 34 determines whether the detected VBUS end actual voltage is consistent with the output voltage designated by the PD spoofer 32 in the charging process, when the detected VBUS end actual voltage is consistent with the output voltage designated by the PD spoofer 32, the MCU chip 34 controls the protection switch 36 to be turned on to realize charging, and when the detected VBUS end actual voltage is inconsistent, the MCU chip 34 controls the protection switch 36 to be turned off to not charge. The protection switch 36 is only connected between the positive pole of the non-fast-charging physical interface 13 and the VBUS terminal, but not between the negative pole of the non-fast-charging physical interface 13 and the ground, but the principle and the effect are the same. The only difference is that the protection switch 36 needs to be cascaded with two MOS transistors, which is relatively costly.
It is worth mentioning that: the MOS tube is used for monitoring whether the charging voltage of the positive electrode and the negative electrode of the non-quick-charging physical interface 13 is abnormal or not, if so, the MOS tube cutting-off loop is controlled by the MCU chip, so that the power supply loop is disconnected to prevent damage caused by abnormal charging, the monitoring and cutting-off protection function is used as an option, the high-power product circuit protection can meet the high-power supply function according to actual requirements, and the MOS tube circuit protection is selected to further improve the safety.
The non-fast-charging physical interface 13 is an interface without performing protocol communication, and is only used for conducting power supply. Specifically, the non-fast-charging physical interface 13 is any one of a DC circular interface, an association square interface, a Pogo pin connector and a pin header, which are all direct-insertion non-fast-charging physical interfaces communicated without an execution protocol, so that the Type-C plug is inserted into the PD adapter 2 to realize output, and any one of the DC circular interface, the association square interface, the Pogo pin connector and the pin header is adopted as output to realize high-power charging of the devices 100 of different models, thereby realizing one-to-one charging use of the devices 100. When the non-fast-charging physical interface 13 adopts a DC circular interface, the Type-C charging wire 1 realizes a Type-C TO DC circular interface; when the non-quick charge physical interface 13 adopts a Pogo pin connector, the Type-C charging wire 1 realizes a Type-C TO Pogo pin connector; when the non-quick-charging physical interface 13 adopts an association square interface, the Type-C charging wire 1 realizes a Type-C TO association square interface; when the non-quick-charging physical interface 13 adopts a pin header, the Type-C charging wire 1 realizes Type-C TO pin header; of course, the non-quick-charging physical interface 13 may be other types of interfaces/connectors, and different interfaces/connectors may be selected according to actual use requirements. It should be noted that, no matter what type of interface is the non-fast-charging physical interface 13, the final purpose is to output high power to the notebook computer or other devices 100 to perform fast-charging.
The non-fast-charging physical interface 13 may be identified by the ID of the device 100 through a resistor, a voltage, or a current, and when the value of the resistor, the voltage, or the current of the non-fast-charging physical interface 13 matches the value of the resistor, the voltage, or the current set by the device 100, the non-fast-charging physical interface 13 is turned on with the device 100 to charge the device 100.
Specifically, when the non-fast-charging physical interface 13 can identify the ID with the device 100 through the resistor, a resistor is connected to the non-fast-charging physical interface 13, when the non-fast-charging physical interface 13 is inserted into the interface of the device 100, the interface of the device 100 can detect the resistance value of the resistor, when the resistance value of the resistor is matched with a preset resistance value, the non-fast-charging physical interface 13 is conducted with the interface of the device 100, at this time, the non-fast-charging physical interface 13 charges the device 100, and the scheme can avoid that the device 100 is abnormally charged by a non-matched PD adapter and a Type-C charging line, so that the device 100 is not normally charged according to a PD protocol to damage the device 100 or the device 100 is abnormal.
In summary, the present invention realizes the fast charge protocol communication with the PD adapter 2 by the MCU chip 34 in combination with the PD decoy 32 and the electronic tag chip 33, and the PD decoy 32 and the electronic tag chip 33 in combination with the PD adapter realize the high-power fast charge protocol communication exceeding 100W, and control the PD adapter 2 to output the specified voltage to the non-fast charge physical interface 13 of the Type-C charging wire 1 for the non-execution protocol communication, and output different powers according to different fast charge protocols through the non-fast charge physical interface 13 to charge the device 100 with high power or non-high power. Therefore, the invention can realize the high-power quick charge function of the PD for the equipment 100 without the quick charge physical interface by matching the Type-C charging wire 1 with the PD adapter 2, solve the problem that the non-quick charge physical interface of the equipment 100 can not communicate with the quick charge protocol, and carry out protocol communication with the PD adapter 2 by the Type-C plug 12 of the Type-C charging wire 1 to output high-power charging, and the current and the voltage can output larger values, for example: the non-fast-charging physical interface 13 at the output end of the type-C charging line 1 is used as a pure interface connection device 100 without executing protocol communication, and outputs different powers according to different fast-charging protocols through the non-fast-charging physical interface 13 to charge the device 100 with high power or non-high power so as to meet different charging requirements. For example, the invention can be applied to the device 100 and hardware with high power of 65W-240W of PD and the specific device 100 with more than 240W to charge the device 100 with high power output, and the invention can be compatible with low power (below 65W) output at the same time, in addition, when the high power fast charging protocol is not conducted, the output is required below the normal power of 100W, and the low power output can be closed and controlled at the same time.
