[0050] Please refer to the appendix. Figure 1 The example illustrates the internal circuitry associated with two charging interfaces in the relevant art. In this example, the terminal device has two Type-C interfaces, namely a Type-C-A interface and a Type-C-B interface. Both Type-C interfaces have a DP / M pin, a VBUS pin, and a CC1 / 2 pin. The DP / M pin is used for data transmission (e.g., USB 2.0) and communication with common charging protocols (e.g., BC1.2). The VBUS pin is used for transmitting electrical energy in scenarios such as forward charging, reverse charging, and reverse power supply. The CC1 / 2 pin is used for communication with fast charging protocols (e.g., PD protocol).

[0051] In this example, the terminal device has a Main charger chip with CC1 / 2 pins, DP / M pins, and VBUS pins. The VBUS pin is connected to the VBUS pins of the Type-C-A interface and the Type-C-B interface, respectively, to provide a normal charging path for the two interfaces, i.e., selecting the power input from the VBUS pin of one interface to charge the battery. The DP / M pin is connected to the DP / M pin of the Type-C-A interface for data transmission (e.g., USB 2.0) and communication with devices connected to the Type-C-A interface using normal charging protocols (e.g., BC1.2). The CC1 / 2 pin is connected to the CC1 / 2 pin of the Type-C-A interface for communication with devices connected to the Type-C-A interface using fast charging protocols (e.g., PD protocol).

[0052] In this example, the terminal device has a Fast charger chip with VBUS pin, VBUS-DRVA pin, VBUS-SENSEA pin, VBUS-DRVB pin, and VBUS-SENSEB pin. The VBUS pin is connected to the VBUS pin of the Type C-A interface and the VBUS pin of the Type C-B interface, respectively, to provide a fast charging path for the two interfaces, that is, to select the power input from the VBUS pin of one interface to charge the battery; the VBUS-DRVA pin and the VBUS-SENSEA pin are used for voltage detection and on / off control of the Type C-A interface; the VBUS-DRVB pin and the VBUS-SENSEB pin are used for voltage detection and on / off control of the Type C-B interface.

[0053] In this example, the terminal device has a PDHTY module and a BC1.2 module. The PDHTY module is connected to the CC1 / 2 pin of the Type C-B interface and is used to communicate with the device connected to the Type C-B interface using fast charging protocols (such as the PD protocol). The BC1.2 module is connected to the DP / M pin of the Type C-B interface and is used to communicate with the device connected to the Type C-A interface using data transmission (such as USB 2.0) and ordinary charging protocols (such as BC1.2).

[0054] In this example, the terminal device has BOOST_A, OCP_A, and OVP_A connected in sequence. OVP_A is connected to the VBUS pin of the Type-C-A interface. BOOST_A, OCP_A, and OVP_A provide reverse charging functionality for the Type-C-A interface.

[0055] In this example, the terminal device has BOOST_B, OCP_B, and OVP_B connected in sequence. OVP_B is connected to the VBUS pin of the Type-C-B interface. BOOST_B, OCP_B, and OVP_B provide reverse charging functionality for the Type-C-B interface.

[0056] In this example, the terminal device has a switch, one end of which is connected to the DP / M of the Type C-A interface and the DP / M of the Type C-B interface respectively, and the other end is connected to the AP, which is used to switch the data channel between the Type C-A interface and the Type C-B interface.

[0057] As can be seen from the above examples, the charging architecture in the relevant technologies is complex and chaotic, with many discrete components, occupying a lot of space, and can only support charging through one charging port at a time, rather than enabling two charging ports to charge the terminal simultaneously.

[0058] Based on the aforementioned technical problems, in a first aspect, at least one embodiment of this disclosure provides a charging architecture, the architecture comprising: a first charging circuit, including a first charging module, a second charging module, a first driving module, a second driving module, a first communication module, and a second communication module; a first interface, connected to the first charging module, the first driving module, and the first communication module respectively, wherein the first charging module is used to charge the battery of a terminal device with electrical energy input from the first interface, the first driving module is used to control the connection and disconnection between the first interface and the first charging module, and the first communication module is used to communicate with the device connected to the first interface using a charging protocol; and a second interface, connected to the second charging module, the second driving module, and the second communication module respectively, wherein the second charging module is used to charge the battery of the terminal device with electrical energy input from the second interface, the second driving module is used to control the connection and disconnection between the second interface and the second charging module, and the second communication module is used to communicate with the device connected to the second interface using a charging protocol.

[0059] In the appendix Figure 2In the example shown, the first charging module, the first driving module, and the first communication module are integrated into a single general-purpose charging chip IC_A; the second charging module, the second driving module, and the second communication module are integrated into another general-purpose charging chip IC_B. In this example, the first interface is a Type-C-A interface, and the second interface is a Type-C-B interface. Both Type-C interfaces have DP / M pins, VBUS pins, and CC1 / 2 pins. The DP / M pin is used for data transmission (e.g., USB 2.0) and communication with common charging protocols (e.g., BC1.2). The VBUS pin is used for transmitting electrical energy in scenarios such as forward charging, reverse charging, and reverse power supply. The CC1 / 2 pin is used for communication with fast charging protocols (e.g., PD protocol). Within the general-purpose charging chip in this example, the charging module is connected to the chip's VBUS pin, the driving module is connected to the chip's VBUS_SENSEA pin and VUBS_DRVA pin respectively, and the communication module is connected to the chip's DP / M pin.

[0060] In another example, the first charging module, the first driving module, the first communication module, the second charging module, the second driving module, and the second communication module are integrated into a single unit as shown in the attached diagram. Figure 3 The example shows a standard charging chip. Within this example chip, a first charging module (Converter Control_A) is connected to the chip's VBUS_A pin, a second charging module (Converter Control_B) is connected to the chip's VBUS_B pin, a first driver module (Driver_A) is connected to the chip's VBUS_SENSEA pin and VUBS_DRVA pin, a second driver module (Driver_B) is connected to the chip's VBUS_SENSEB pin and VUBS_DRVB pin, a first communication module is connected to the chip's DP_A pin and DM_A pin, and a second communication module is connected to the chip's DP_B pin and DM_B pin.

[0061] In addition, the first charging circuit is also used to reverse power supply or charge devices connected to the first and second interfaces based on the battery of the terminal device. For example, see attached... Figure 2 In the example shown, the ordinary charging chip IC_A provides reverse power or charging for devices connected to the Type-C-A interface, and the ordinary charging chip IC_B provides reverse power or charging for devices connected to the Type-C-B interface. For example, see attached... Figure 3 The standard charging chip shown is used to provide reverse power or charge devices connected to the Type-C-A and Type-C-B interfaces.

[0062] This embodiment uses two interfaces as an example to illustrate the structure of a charging architecture that "sets an independent charging module, driving module, and communication module for each interface." By setting an independent charging module, driving module, and communication module for each interface within the first charging circuit, it is possible to independently provide functions such as power transmission, on / off control, and protocol communication for each device connected to the interface (e.g., a charger). This allows each device connected to the interface (e.g., a charger) to independently charge the battery of the terminal device without interfering with each other. In other words, this charging architecture enables multiple charging interfaces of the charging device to charge the terminal device simultaneously, improving the charging efficiency of the terminal device and the utilization rate of each charging interface. Furthermore, the charging module, driving module, and communication module of each interface, as well as the functional modules responsible for reverse charging and power supply of the interface, are all integrated into the first charging circuit, reducing the circuit complexity of the charging architecture.

[0063] Furthermore, it should be understood that the first and second interfaces in the above embodiments do not constitute a limitation on the number of charging interfaces in the charging architecture. The charging architecture can be equipped with three or more charging interfaces, and each charging interface can be equipped with an independent charging module, driving module and communication module.

[0064] In one possible embodiment of this disclosure, the first communication module includes a first charging unit connected to a pin for data transmission of the first interface, for transmitting data and communicating the charging protocol of the first charging module; the second communication module includes a second charging unit connected to a pin for data transmission of the second interface, for transmitting data and communicating the charging protocol of the second charging module.

[0065] The first and second charging modules can be ordinary charging modules, capable of providing charging power of ordinary power (e.g., the charging power provided by the BC1.2 charging protocol). In this embodiment, the charging power of the first and second charging modules is less than that of the third charging module.

[0066] For example, the pin used for data transmission can be a DP / M pin.

[0067] In the appendix Figure 2In the example shown, the first charging unit is connected to the DP / M pin of IC_A, and the DP / M pin of IC_A is connected to the DP / M pin of TypeC-A. This enables the first charging unit of IC_A to transmit data and communicate the charging protocol of the first charging module with the device connected to TypeC-A. The second charging unit is connected to the DP / M pin of IC_B, and the DP / M pin of IC_B is connected to the DP / M pin of TypeC-B. This enables the second charging unit of IC_B to transmit data and communicate the charging protocol of the second charging module with the device connected to TypeC-B.

[0068] In the appendix Figure 3 In the example shown, the first charging unit BC1.2_A is connected to the DP_A and DM_A pins of the chip, respectively. The DP_A and DM_A pins of the chip are connected to the DP / M pins of Type C-A, respectively. This enables the first charging unit BC1.2_A to transmit data and communicate the charging protocol of the first charging module with the device connected to Type C-A. The second charging unit BC1.2_B is connected to the DP_B and DM_B pins of the chip, respectively. The DP_B and DM_B pins of the chip are connected to the DP / M pins of Type C-B, respectively. This enables the second charging unit BC1.2_B to transmit data and communicate the charging protocol of the second charging module with the device connected to Type C-B, respectively.

[0069] Based on this embodiment, the architecture also includes a switching switch. One end of the switching switch is connected to the processor of the terminal device, and the other end is connected to the first charging unit and the second charging unit respectively. The switching switch is used to connect the first charging unit or the second charging unit to the processor so that the first charging unit or the second charging unit can transmit data with the processor.

[0070] In the appendix Figure 2 In the example shown, the switch is a Switch with its input A connected to the DP / M pin of Type C-A, its input B connected to the DP / M pin of Type C-B, and its output connected to the processor AP. The Switch can switch between the DP / M pin of Type C-A and the DP / M pin of Type C-B to switch the interface for data transmission with the AP, that is, to enable devices on one interface to transmit data with the AP and to switch between interfaces.

[0071] In the appendix Figure 3In the example shown, the switch is integrated into the charging chip. Its input terminals are connected to the first charging unit BC1.2_A and the first charging unit BC1.2_B, respectively, and then to the DP / M pins of Type C-A and Type C-B, respectively. Its output terminals are connected to the DP_COM pin and DM_COM pin used for data transmission with the processor, and then to the processor AP. Thus, the switch can switch between the DP / M pins of Type C-A and Type C-B to switch the interface for data transmission with the AP, that is, to enable devices on one interface to transmit data with the AP and to switch between interfaces.

[0072] In one possible embodiment of this disclosure, the architecture further includes a second charging circuit, which includes a third charging module, a third driving module, and a fourth driving module. The third charging module is connected to the first interface and the second interface respectively, and is used to charge the battery of the terminal device with electrical energy input from the first interface or the second interface at a charging power higher than that of the first charging module and the second charging module. The third driving module is connected to the first interface and is used to control the connection and disconnection between the first interface and the third charging module. The fourth driving module is connected to the second interface and is used to control the connection and disconnection between the second interface and the third charging module.

[0073] The third charging module can be a fast charging module, which can provide high-power charging (such as the charging power provided by the PD charging protocol).

[0074] For example, the power supply pin of the first interface is connected to the third charging module in sequence through a first switch and a second switch. The first charging module is connected to the line between the first switch and the second switch. The first driving module is used to control the on / off state of the first switch, and the third driving module is used to control the on / off state of the second switch.

[0075] When the first switch is on and the second switch is off, the power supply pin of the first interface is connected to the first charging module. When both the first and second switches are on, the power supply pin of the first interface is connected to the third charging module. When both the first and second switches are off, the power supply pin of the first interface is not connected to any charging module. For example, the power supply pin can be the VBUS pin.

[0076] For example, the first driving module has a first detection pin and a first driving pin. The first detection pin is connected to a power supply pin of the first interface, and the first driving pin is connected to the control electrode of the first switch. The third driving module has a third detection pin and a third driving pin. The third detection pin is connected to a power supply pin of the first interface, and the third driving pin is connected to the control electrode of the second switch.

[0077] In the appendix Figure 2 In the example shown, the third charging module is a Fast charger chip, which has VBUS pins, VBUS-DRVA pin, VBUS-SENSEA pin, VBUS-DRVB pin, and VBUS-SENSEB pin. The VBUS pin of the Type-C-A interface is connected to the VBUS pin of the Fast charger chip through the first switch Q1 and the second switch Q2. The first detection pin is the VBUS-SENSEA pin of IC_A, which is connected to the VBUS pin of the Type-C-A interface; the first drive pin is the VBUS-DRVA pin of IC_A, which is connected to the control electrode of the first switch Q1. The third detection pin is the VBUS-SENSEA pin of the Fast charger chip, which is connected to the VBUS pin of the Type-C-A interface; the third drive pin is the VBUS-DRVA pin of the Fast charger chip, which is connected to the control electrode of the second switch Q2.

[0078] For example, the second drive module has a second detection pin and a second drive pin. The second detection pin is connected to the power supply pin of the second interface, and the second drive pin is connected to the control electrode of the third switch. The fourth drive module has a fourth detection pin and a fourth drive pin. The fourth detection pin is connected to the power supply pin of the second interface, and the fourth drive pin is connected to the control electrode of the fourth switch.

[0079] In the appendix Figure 2In the example shown, the VBUS pin of the Type-C-B interface is connected to the VBUS pin of the Fast charger chip via the third switch Q3 and the fourth switch Q4. The second detection pin is the VBUS-SENSEB pin of IC_B, which is connected to the VBUS pin of the Type-C-B interface; the second drive pin is the VBUS-DRVB pin of IC_B, which is connected to the control electrode of the third switch Q3. The fourth detection pin is the VBUS-SENSEB pin of the Fast charger chip, which is connected to the VBUS pin of the Type-C-B interface; the fourth drive pin is the VBUS-DRVB pin of the Fast charger chip, which is connected to the control electrode of the fourth switch Q4.

[0080] Based on this embodiment, the first communication module includes a third charging unit, which is connected to the pin of the first interface for protocol communication, and is used to communicate the charging protocol of the third charging module; the second communication module includes a fourth charging unit, which is connected to the pin of the second interface for protocol communication, and is used to communicate the charging protocol of the third charging module.

[0081] For example, the pin used for protocol communication is the CC1 / 2 pin.

[0082] In the appendix Figure 2 In the example shown, the third charging unit can be connected to the CC1 / 2 pin of IC_A, which in turn is connected to the CC1 / 2 pin of Type C-A. This enables the third charging unit of IC_A to communicate with the device connected to Type C-A using fast charging protocols, such as the PD protocol. Similarly, the fourth charging unit can be connected to the CC1 / 2 pin of IC_B, which in turn is connected to the CC1 / 2 pin of Type C-B. This enables the fourth charging unit of IC_B to communicate with the device connected to Type C-B using fast charging protocols, such as the PD protocol.

[0083] In the appendix Figure 3In the example shown, the third charging unit PDPHY_A is connected to the chip's CC1_A and CC2_A pins, respectively. The chip's CC1_A and CC2_A pins are connected to the CC1 / 2 pins of Type C-A, thereby enabling PD protocol communication between the chip's third charging unit PDPHY_A and the device connected to Type C-A. Similarly, the fourth charging unit PDPHY_B is connected to the chip's CC1_B and CC2_B pins, respectively.
