Abstract

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.
