Abstract

The invention provides a processing circuit and method for multiple power supply ports and electronic equipment, the processing circuit comprises N control modules and a bus; each control module is used for being correspondingly connected with one power supply port, and a communication interface of each control module is connected to the bus; the bus is connected with a power ground through a busresistor, and the bus is a single-wire bus; the control module can send a numerical signal to the bus; the change amplitude of the first physical quantity of the bus signal on the bus is associated with the first physical quantity or the second physical quantity of all the target signals sent to the bus. The control module can also detect a first physical quantity of a bus signal on the bus through the communication interface, and adjust the working parameters of the connected power supply port according to the change amplitude of the detected first physical quantity.

Description

technical field [0001] The invention relates to the field of power supply, in particular to a processing circuit, method and electronic equipment for multiple power supply ports. Background technique [0002] In an electronic device with multiple power supply ports, different power supply ports (such as USB ports) can be used to supply power to the outside, thereby playing the role of power consumption and / or charging. However, the power supply resources of the device (such as the total rated power) are Fixed, therefore, it is necessary to allocate power supply resources (such as actual output power) of each power supply port, which may be dynamically allocated or fixedly allocated. Among them, the premise of allocation is to be able to accurately know the power supply information (such as its power, voltage, current, etc.) of the power supply port. Each power supply port can supply power under the control of the corresponding port controller, so the power supply informatio...
