[0020] The protocol control circuit is used to acquire charging protocol information of at least two loads when detecting that the plurality of output interfaces of the data line are connected with the at least two loads, and control the voltage regulating circuit to output a first voltage corresponding to each output interface through the output interface connected with each load in the at least two loads respectively according to the charging protocol information; the first voltage corresponding to each output interface is the same as the charging protocol voltage of the load connected with each output interface.

[0021] In the embodiments of the present application, the input interface of the data line is used to connect with the adapter to acquire the voltage inputted by the data line from the adapter.

[0022] In the embodiments of the present application, the wired interface of the data line can be set as a Mini USB interface, a Micro USB interface, a USB Type-C interface, and a Lightning interface, etc. The wireless interface can be set as a watch wireless interface and a mobile phone wireless interface, etc. In actual application, the output interface of the data line can also be set as other charging interfaces, which is not limited in the embodiments of the present application.

[0023] Based on this, in an optional embodiment of the present application, the wireless interface includes: a watch wireless interface and a mobile phone wireless interface.

[0024] Figure 2 Structure diagram of the control circuit provided by the embodiment of the present application Figure 2 As shown in the figure, in this embodiment, the control circuit includes a protocol control circuit, a voltage regulating circuit and an input circuit, the control circuit further includes an input circuit, and the input circuit is connected with the voltage regulating circuit and the input interface. Figure 3

[0025] The input circuit is configured to transmit the voltage inputted by the adapter into the input circuit to the voltage regulating circuit.

[0026] The protocol control circuit is connected with a plurality of output interfaces of the data line, and when the output interface is connected with a load, the load can perform protocol handshake with the protocol control circuit through the output interface. The protocol control circuit detects the charging protocol information of each load connected with the data line, and the charging protocol information includes charging protocol current, charging protocol voltage, charging protocol power and the like. The protocol control circuit controls the voltage regulating circuit to output the charging protocol voltage required by each load according to the charging protocol information of each load.

[0027] Figure 3 The structure diagram of the voltage regulating circuit provided by the embodiment of the present application is shown in the figure. Figure 4 As shown in the figure, the voltage regulating circuit includes n voltage regulating sub-circuits, the data line includes n output interfaces, one voltage regulating sub-circuit is arranged on each output line of the data line, and the n voltage regulating sub-circuits correspond to the n output interfaces one by one.

[0028] Based on this, in an optional embodiment of the present application, the voltage regulating circuit includes a plurality of voltage regulating sub-circuits, and the plurality of voltage regulating sub-circuits are connected with the plurality of output interfaces one by one.

[0029] In actual application, the input circuit can transmit the voltage received from the adapter to each voltage regulating sub-circuit in the at least two voltage regulating sub-circuits.

[0030] In the embodiment of the present application, the power of the watch wireless charging is smaller than the power of the mobile phone wireless charging, so the output voltage of the voltage regulating sub-circuit corresponding to the mobile phone wireless charging can be used as the input voltage of the voltage regulating sub-circuit corresponding to the watch wireless charging, thereby avoiding that the watch wireless charging directly obtains power supply from the input circuit and reducing the consumption of resources.

[0031] Based on this, in an optional embodiment of the present application, the voltage input end of the voltage regulating sub-circuit corresponding to the watch wireless interface is connected with the voltage output end of the voltage regulating sub-circuit corresponding to the mobile phone wireless interface, so that the voltage regulating sub-circuit corresponding to the watch wireless interface receives the input voltage. ​

[0032] In the implementation of the present application, the wireless charging power of various brands of watches is mostly the same, generally 5W, and the wireless charging power of various brands of mobile phones is mostly the same, generally 15W. Therefore, in actual application, the watch wireless interface corresponding voltage regulating sub-circuit can be set to a fixed output of 5W, and the mobile phone wireless interface corresponding voltage regulating sub-circuit can be set to a fixed output of 15W, without the need for protocol control circuit to control the voltage.

[0033] In the embodiment of the present application, the data line is a one-to-many data line, which can be a one-to-two data line, a one-to-three data line, or other data lines with multiple output interfaces. The wired interface of the data line can be set to the same type of interface, such as a USB Type-C interface, or different types of interfaces. The present application does not limit this.

[0034] In the embodiment of the present application, the voltage regulating sub-circuit is used to boost the input voltage to obtain a voltage of the same size as the charging protocol voltage of the load; or,

[0035] The voltage regulating sub-circuit is used to step down the input voltage to obtain a voltage of the same size as the charging protocol voltage of the load; or,

[0036] The voltage regulating sub-circuit is used to input the voltage as a voltage of the same size as the charging protocol voltage of the load.

[0037] The voltage regulating sub-circuit can use a small input voltage to enhance the application scenario of the control circuit. A large input voltage can improve charging efficiency and reduce power loss. When the input voltage and the charging protocol voltage of the load are the same size, the voltage regulating sub-circuit directly inputs the voltage as a voltage of the same size as the charging protocol voltage of the load, which can reduce power loss and reduce circuit heating.

[0038] In the embodiment of the present application, the voltage regulating sub-circuit can use a direct current to direct current converter (DC-DC Converter). In actual application, the voltage regulating sub-circuit can be designed according to the needs, and the present application does not limit this.

[0039] The voltage input to the input circuit of the adapter can be directly transmitted to each voltage regulating sub-circuit. The output voltage of the voltage regulating sub-circuit is connected to the interface, and the protocol control circuit controls the voltage regulating sub-circuit to output a voltage of the same size as the charging protocol voltage of the load.

[0040] In the embodiments of the present application, the protocol control circuit can control the voltage adjustment sub-circuit to adjust the input voltage through a feedback regulation (FB) voltage regulation mode, so that the voltage adjustment sub-circuit adjusts the input voltage to a voltage of the same size as the charging protocol voltage of the load and charges the load.

[0041] Based on this, in an optional embodiment of the present application, the protocol control circuit is configured to control the voltage adjustment sub-circuit to adjust the input voltage to a voltage of the same size as the charging protocol voltage of the load through an FB voltage regulation mode.

[0042] In the embodiments of the present application, the protocol control circuit can also determine the voltage size received from the adapter according to the charging protocol information of each load connected to the data line, thereby improving the flexibility of the control circuit design and making the application scope wider. After determining the voltage size received from the adapter, the protocol control circuit interacts with the input circuit and sends voltage information to the input circuit, where the voltage information includes the determined voltage size information. After receiving the voltage information, the input circuit interacts with the adapter and sends the voltage information to the adapter, so that the voltage output by the adapter is the voltage size determined by the protocol control circuit.

[0043] Based on this, in an optional embodiment of the present application, the protocol control circuit is connected to the input circuit.

[0044] The protocol control circuit is configured to determine the voltage size of the input circuit of the adapter according to the charging protocol information of each load in the at least two loads, and generate voltage information, where the voltage information contains the determined voltage size information of the input circuit of the adapter, and send the voltage information to the input circuit.

[0045] The input circuit is configured to receive the voltage information sent by the protocol control circuit, send the voltage information to the adapter, and receive a voltage of the same size as the determined voltage size of the input circuit of the adapter from the adapter.

[0046] For example, the protocol control circuit determines the voltage of the highest charging protocol voltage among the multiple loads connected to the data line as the voltage output by the adapter. In this example, when the voltage output by the adapter is the same as the charging protocol voltage required by the load, the voltage adjustment sub-circuit directly takes the voltage size output by the adapter as the output voltage of the voltage adjustment sub-circuit to charge the load. When the voltage output by the adapter is greater than the charging protocol voltage required by the load, the voltage adjustment sub-circuit reduces the voltage input to the voltage adjustment sub-circuit to the size of the charging protocol voltage and then charges the load.

[0047] Based on this, in an optional embodiment of the present application, the protocol control circuit is configured to take the voltage with the highest charging protocol voltage among the at least two loads as the determined voltage of the adapter inputting the input circuit.

The wired interface one and the wired interface two are USB Type-C interfaces, the wireless interface one is a 5W watch wireless charging module, and the wireless interface two is a 15W mobile phone wireless charging module.

[0049] When the wireless interface one, the wireless interface two, the wired interface one and the wired interface two are connected with loads, the protocol control circuit performs protocol handshake with the loads connected with the wireless interface two, the wired interface one and the wired interface two through CC line or DP / DM line. The protocol control circuit detects charging protocol information of each load, determines a second voltage as the size of the voltage output by the adapter according to the charging protocol voltage of each load, the second voltage being the maximum charging protocol voltage among the loads, generates voltage information containing information related to the size of the voltage output by the adapter, and sends the voltage information to the input circuit. The input circuit interacts with the adapter, sends the voltage information to the adapter, receives the voltage output by the adapter with the same size as the second voltage, and transmits the voltage output by the adapter to the voltage regulation sub-circuit two, the voltage regulation sub-circuit three and the voltage regulation sub-circuit four. The voltage output by the voltage regulation sub-circuit two is transmitted to the voltage regulation sub-circuit one and the wireless interface two, and the voltage regulation sub-circuit two outputs a fixed 15W power. The voltage regulation sub-circuit one outputs a fixed 5W power, which can be set to 5V1A for example.
