Design and simulation of the timing control system for power on board

Abstract： In view of the complexity and high cost of most board power on timing control systems at this stage, this paper designs a board power on timing control system based on a single chip microcomputer, which realizes the power on timing control of multiple power supplies, voltage and current monitoring, etc. This design has the advantages of high cost performance, simple control system, and high stability. Proteus and Keil software are used to build a joint simulation platform to simulate the power on timing control system, which lays a foundation for its practical application.
