[0004] However, in the process of increasing the equivalent resistance, the voltage of the configured channel in the connecting line will also be pulled up, which may cause the mobile phone to reach the overvoltage detection point. When the mobile phone reaches the overvoltage detection point, it will Into the overvoltage protection, charging cannot be carried out; in addition, the charging ability of the mobile phone cannot be accurately detected only by detecting the voltage and current, for example, when the circuit is undervoltage, power-off, etc., the charging ability cannot be accurately detected

The application provides a communication protocol authentication device and a connecting line, which belong to the technical field of charging authentication. The device includes: a connection port, an authentication unit and a clamping protection module; the authentication unit and the clamping protection module are respectively connected with the connection port; the authentication unit is used for changing the connection state of the connection port and the connection wire body The authentication process includes: switching of the equivalent resistance, power-down detection, under-voltage detection, and power supply in a power-off state; the clamping protection module is used to clamp the output voltage of the device within a preset voltage range. In the present application, the clamping protection module can be set to realize the clamping limitation of the voltage, thereby preventing the mobile phone terminal from entering the overvoltage protection; the accuracy of the detection of the charging capability of the mobile phone can be improved through the authentication unit.
Description
technical field [0001] The present application relates to the technical field of charging authentication, and in particular, to a communication protocol authentication device and a connecting line. Background technique [0002] When the charging head charges the mobile phone, it is necessary to interact with the mobile phone through the connecting line to determine the charging ability of the charging head to the mobile phone. [0003] In the prior art, the equivalent resistance is usually set in the connecting wire. When the charging head and the mobile phone are connected by the connecting wire, the equivalent resistance will increase to realize the increase of the voltage of the connecting wire, so as to realize the voltage of the charging head. certification to enable charging. In addition, in the prior art, the verification of the charging capability of the mobile phone is only realized by arranging a circuit for voltage detection or current detection. [0004] Howeve...
