摘要： The invention provides a processing circuit with multiple power supply ports and an electronic device. The processing circuit includes: N power supply ports; a first-level power supply; N middle transmission modules, connected between the first-level power supply and the corresponding power supply port, wherein at least one of which is used as a second-level power supply; and a charging protocol control module. The charging protocol control module is respectively connected to the first-level power supply, the N power supply ports, and the N middle transmission modules. The second-level power supply operates in a switching power mode or a pass through mode. In the pass through mode, the output voltage of the second-level power supply matches the input voltage received by the first-level power supply, and the output voltage of the second-level power supply is not adjustable.

摘要： The present invention provides a processing circuit, a method, and an electronic device for multiple power supply ports. The processing circuit includes N control modules and a bus. Each control module is correspondingly connected to a power supply port. The communication interface of each control module is connected to the bus. The bus is a one-wire bus and is connected to a power line ground through a resistor. The control modules transmit value signals to the bus. The varied range of a first physical quantity of a bus signal carried by the bus is related to first physical quantities or second physical quantities of all target signals transmitted to the bus. The control module detects the first quantity of the bus signal through the communication interface and adjusts the operating parameter of the connected power supply port according to the varied range of the detected first physical quantity.
