[0017] In the embodiment of the present application, the burning device is connected to a host computer (a computer device used to control the burning process) via VDD (the power supply voltage of the digital power chip).

[0018] The burning device includes an input connector and an output connector. The input connector is used to connect to an external power supply or signal, and is connected to the burning device through SCL (serial clock line), SDA (serial data line) and GND (ground line). The output connector is used to output the power supply or signal to a digital power chip or other related components. In addition, the burning device is also equipped with a first switch and a second switch, which are used to control the on and off of the circuit and the selection or switching of different voltages.

[0019] The burning device also includes a BUCK (step-down module), whose main function is to reduce the higher input voltage to the required lower voltage, that is, to convert the input 5V voltage into the required 3.3V voltage. The first switch controls the direct output of 5V voltage, and the second switch controls the 3.3V voltage output after the BUCK step-down to ensure that the digital power chip can obtain a stable operating voltage. In order to realize the transmission of data and power, the device is equipped with a USB interface, through which the burning device is connected to the host computer to realize control and data transmission.

[0020] In terms of specific circuit design, the burning device includes a first burning circuit and a first transmission circuit, which are respectively connected to the digital power chip. The main function of the first burning circuit is to provide the controllable voltage required for burning to ensure that VDD can remain stable during the burning process. The first transmission circuit is used to realize data transmission between the host computer and the digital power chip, using the I2C protocol (a protocol for data communication between chips) to ensure the accuracy and reliability of instructions and data transmission during the firmware burning process.

[0021] When the burning device is working, it obtains power and data from the host computer through the USB interface. The host computer sends the burning instruction through the USB to I2C tool.

Then the output connector is connected to the digital power chip to transmit the I2C signal and the ground wire. The host computer sends control instructions and data through a USB interface, and the USB interface is connected to a USB to I2C tool to convert the USB signal into an I2C signal. The converted I2C signal is transmitted to the I2C circuit in the burning device through the SCL and SDA lines of the input connector.

[0029] The first burning circuit includes a first burning sub-circuit and a second burning sub-circuit; the first burning sub-circuit includes a host computer, an input connector, an output connector, a first switch, a USB and a VDD.

[0030] In an embodiment of the present application, the first burning circuit is composed of a first burning sub-circuit and a second burning sub-circuit. The core components of the first burning sub-circuit include a host computer, an input connector, an output connector, a first switch, a USB interface and VDD. First, the host computer is a computer device for controlling the burning process, which is connected to the burning device through a USB interface, provides power and sends a burning instruction. The USB interface is not only responsible for data transmission, but also provides necessary power support. The input connector is used to access an external power supply or signal, and is connected to the burning device through SCL, SDA and GND. The input connector transmits these signals to the inside of the burning device. In the burning device, the first burning sub-circuit controls the voltage output through the first switch. The function of the first switch is to directly output a 5V voltage. When the first switch is closed, the voltage is directly output as 5V. The output connector outputs the regulated voltage and control signal to the VDD of the digital power chip to ensure the stability and reliability of the voltage during the burning process.

[0031] Furthermore, the device provided in the application embodiment also includes:

[0032] The second programming sub-circuit includes a host computer, an input connector, an output connector, a second switch, a BUCK, a USB and a VDD.

[0033] In the embodiment of the present application, the second burning sub-circuit includes a host computer, an input connector, an output connector, a second switch, a BUCK, a USB interface and VDD. The host computer provides power through the USB interface and sends a burning instruction. The input connector is connected to an external I2C signal and transmits these signals to the burning device. The second burning sub-circuit converts the 5V voltage into a 3.3V voltage through the BUCK module and selects the output through the second switch. The regulated 3.3V voltage is transmitted to the VDD of the digital power chip through the output connector to ensure voltage stability and reliability during the burning process.

When the first switch is closed, the circuit directly outputs a 5V voltage, which is provided to the VDD of the digital power chip, which is the first voltage value.

[0037] On the other hand, the second burning subcircuit is also under the control of the host computer, connected and powered through the USB interface.

During the burning process, the post-stage in-situ detection module first checks whether the physical connection and signal transmission between the burning device and the digital power chip are normal. The detection module determines the communication state by monitoring the integrity and stability of the I2C signal. After the burning device establishes normal I2C communication with the digital power chip, the post-stage in-situ detection module will confirm that the connection is stable. If the test result shows that the communication is normal, that is, the signal transmission is correct and the connection is stable, the post-stage in-situ detection module will send an indication to the host computer, indicating that the system is ready. Once a confirmation signal from the post-stage in-situ detection module is received, the host computer will obtain and send a start burning instruction. At this point, the burning device starts to execute the firmware burning operation. All data transmission and instruction execution in the burning process are completed through the I2C bus to ensure that the firmware is correctly written into the digital power chip.
