A modular power management system for electronic devices

Abstract

The utility model provides a kind of modular electronic equipment power supply management system, comprising: main controller, at least two pluggable power modules, centralized protection module and dynamic balancing module;The main controller is respectively electrically connected with the identity recognition unit of each pluggable power module by SPI bus, and the output end of each pluggable power module is connected to the input end of centralized protection module after being converged by copper bar;The centralized protection module includes self-restoring fuse in series in the copper bar and overvoltage detection circuit connected with the IO port of main controller, and its output end is connected to load bus;The dynamic balancing module is connected between load bus and ground in parallel, and its control end is connected to the output pin of main controller through PWM signal line;The power supply pin of main controller is respectively electrically connected with the 3.3V output end of pluggable power module, the auxiliary power supply interface of centralized protection module, and the utility model can solve the deficiency of existing fixed architecture in adaptability and maintainability.
