Description

Technical Field

[0001] This utility model relates to the field of data cable technology, and in particular to a charging circuit and a novel charging data cable. Background Technology

[0002] During daily charging, power transfer typically requires the cooperation of two key players: the transmitter and the receiver. The transmitter provides power, while the receiver receives and utilizes that power for charging. Coordination and communication between them are crucial for ensuring the efficiency and safety of the charging process. Power transfer between the transmitter and receiver is based on a series of complex communication protocols, such as USB Power Delivery (USB PD). When a receiving device (such as a smartphone) connects to a transmitting device (such as a charger), the two communicate via a data cable to negotiate power transfer parameters. The transmitting device adjusts its output voltage and current according to the receiving device's needs to ensure adequate power delivery. Simultaneously, the protocol chip continuously monitors the process, providing overvoltage, overcurrent, and overheat protection to ensure safe charging.

[0003] As the number of receiving devices increases, related technologies typically use a dual-connector charging cable to charge two devices simultaneously. However, the charging power of these dual-connector charging cables is relatively low, failing to meet users' actual needs for fast charging. Utility Model Content

[0004] Therefore, it is necessary to address the problem that the charging power of dual-channel charging cables in related technologies is low and cannot meet the actual needs of users for fast charging, and to provide a new charging circuit and a new charging cable.

[0005] A new type of charging data cable charging circuit includes an input interface, a first output interface and a second output interface. The input interface is used to connect to a power data terminal, and the first output interface and the second output interface are both used to connect to a power consumption data terminal. The input interface, the first output interface and the second output interface are all Type-C interfaces.

[0006] The input interface is connected to the voltage regulator module and the main control module respectively. The voltage regulator module is connected to the first DC adjustment module and the second DC adjustment module respectively. The main control module is connected to the first charging management module and the second charging management module respectively. The first charging management module is connected to the first output interface. The second charging management module is connected to the second output interface. The first DC adjustment module is connected to the first charging management module. The second DC adjustment module is connected to the second charging management module.

[0007] Both the first charging management module and the second charging management module support the PD3.1 protocol.

[0008] When the charging circuit of the aforementioned novel charging data cable is in operation, the power data terminal provides an initial voltage signal through the input interface. This initial voltage signal is regulated by the voltage regulator module and then provided to the first DC adjustment module and the second DC adjustment module. The first DC adjustment module generates a first reference voltage signal based on the initial voltage signal and provides it to the first charging management module. The second DC adjustment module generates a second reference voltage signal based on the initial voltage signal and provides it to the second charging management module. The first charging management module generates a first power supply signal based on the first reference voltage signal and provides it to the power user data terminal through the first output interface. The second charging management module generates a second power supply signal based on the second reference voltage signal and provides it to the power user data terminal through the second output interface. Furthermore, the first and second charging management modules can also determine the device type and charging protocol of the power user data terminal through the first and second output interfaces, respectively, and send the device type and charging protocol to the main control module. The main control module communicates the charging protocol with the power data terminal through the input interface. In practical applications, either the first or second output interface can be connected to a power data terminal; alternatively, the first and second output interfaces can be connected to different power data terminals simultaneously. Since both the first and second charging management modules support the PD3.1 protocol, the first and second output interfaces have high charging efficiency, meeting users' fast charging needs.

[0011] In one embodiment, the main control module includes a main control chip, which includes CC1 pin, CC2 pin, D+ pin, D- pin, GPIO1 pin and GPIO2 pin;

[0012] The main control chip is connected to the first signal terminal via the CC1 pin, to the second signal terminal via the CC2 pin, to the first charging management module and the second charging management module via the D+ pin, to the first charging management module and the second charging management module via the D- pin, to the first charging management module via the GPIO1 pin, and to the second charging management module via the GPIO2 pin.

[0014] In one embodiment, the second charging management module includes a second charging management chip, which is an RT7209 chip.

[0015] In one embodiment, the first DC adjustment module includes a first DC adjustment chip, which is a JWH6344 chip.

[0016] In one embodiment, the second DC adjustment module includes a second DC adjustment chip, which is a JWH6344 chip.

[0017] In one embodiment, the voltage regulator module includes a voltage regulator chip, which is an RT9072B chip.

The input interface 10 is connected to the voltage regulator module 40 and the main control module 50, respectively. The voltage regulator module 40 is connected to the first DC adjustment module 60 and the second DC adjustment module 70, respectively. The main control module 50 is connected to the first charging management module 80 and the second charging management module 90, respectively. The first charging management module 80 is connected to the first output interface 20, and the second charging management module 90 is connected to the second output interface 30. The first DC adjustment module 60 is connected to the first charging management module 80, and the second DC adjustment module 70 is connected to the second charging management module 90. The first charging management module 80 and the second charging management module 90 both support the PD3.1 protocol.

[0026] When the charging circuit of the aforementioned novel charging data cable is in operation, the power data terminal provides an initial voltage signal through the input interface. This initial voltage signal is regulated by the voltage regulator module and then provided to the first DC adjustment module and the second DC adjustment module. The first DC adjustment module generates a first reference voltage signal based on the initial voltage signal and provides it to the first charging management module. The second DC adjustment module generates a second reference voltage signal based on the initial voltage signal and provides it to the second charging management module. The first charging management module generates a first power supply signal based on the first reference voltage signal and provides it to the power user data terminal through the first output interface. The second charging management module generates a second power supply signal based on the second reference voltage signal and provides it to the power user data terminal through the second output interface. Furthermore, the first and second charging management modules can also determine the device type and charging protocol of the power user data terminal through the first and second output interfaces, respectively, and send the device type and charging protocol to the main control module. The main control module communicates the charging protocol with the power data terminal through the input interface. In practical applications, either the first or second output interface can be connected to a power data terminal; alternatively, the first and second output interfaces can be connected to different power data terminals simultaneously. Since both the first and second charging management modules support the PD3.1 protocol, the first and second output interfaces have high charging efficiency, meeting users' fast charging needs.

[0027] The input interface 10 includes a power supply terminal 11, a ground terminal 12, a first signal terminal 13, and a second signal terminal 14. The power supply terminal 11 is connected to the voltage regulator module 40, the first DC adjustment module 60, and the second DC adjustment module 70, respectively. The ground terminal 12 is connected to the first DC adjustment module 60 and the second DC adjustment module 70, respectively. The first signal terminal 13 and the second signal terminal 14 are connected to the main control module 50, respectively. The power supply terminal 11 is used to provide initial voltage signals to the first DC adjustment module 60 and the second DC adjustment module 70. The ground terminal 12 is used to ground the first DC adjustment module 60 and the second DC adjustment module 70. The first signal terminal 13 and the second signal terminal 14 communicate with the main control module via different channels to establish a charging protocol.

[0028] The main control module 50 includes a main control chip 51, which includes pins CC1, CC2, D+, D-, GPIO1, and GPIO2. The main control chip 51 is connected to the first signal terminal 13 via the CC1 pin, to the second signal terminal 14 via the CC2 pin, to the first charging management module 80 and the second charging management module 90 via the D+ and D- pins, to the first charging management module 80 and the second charging management module 90 via the GPIO1 pin, and to the second charging management module 90 via the GPIO2 pin. Furthermore, the main control chip 51 uses an RT7202KLA chip. The RT7202KLA chip is a power management chip that supports integrated fast charging protocols. It communicates with the power data terminal through the CC1 pin for the first channel of fast charging protocol communication and through the CC2 pin for the second channel of fast charging protocol communication. The D+ and D- pins are only enabled when the PD2.0 protocol is supported. The operating status of the first charging management module 80 and the second charging management module 90 are controlled through the GPIO1 and GPIO2 pins.

It employs a synchronous buck architecture, significantly reducing conduction losses and supporting conversion efficiencies up to 95%, making it suitable for high-current output scenarios.

[0031] The voltage regulator module 40 includes a voltage regulator chip 41, which uses the RT9072B chip. The RT9072B chip is a linear voltage regulator chip with a wide input voltage range, designed specifically for high-voltage, low-current load scenarios. With its wide input voltage range, reverse connection protection, and high reliability, it is an ideal choice for high-voltage, low-current applications, especially suitable for industrial and battery systems with stringent power safety and stability requirements.
