摘　　要：随着电子技术的不断发展,现代电子器件具有复杂的供电要求,包括CPU、DSP、微控制器、FPGA等的电子系统,需要多路电源供电以及特定的电源排序。提出了一个基于UCD9081的电源排序、电压监视的电源管理设计方案,对UCD9081的特性及工作原理进行了简单介绍,并给出了实现该设计的具体步骤。UCD9081不但可以对多路电源自主进行排序和监视,而且能够与其它器件协调,无缝地监视系统中多路电源稳压器,提供故障和复位管理。当系统连接到I2C总线时,可以运用功能强大、基于PC的图形用户界面GUI,实时配置系统,实现系统可视化并调试系统。With the continuous development of electronic technology,modern electronic components have complex power supplying requirements,electronic systems that include CPU,DSP,microcontroller,FPGA,and so forth,require the multiple power supplies and specific power sequencing.This paper proposes a power supplying management design scheme of power sequencing and voltage monitoring based on UCD9081,briefly introduces the characteristics and operating principle of UCD9081,and gives the specific steps to realize the design.UCD9081 not only automates the sequencing and monitoring of the multiple power supplies,but also coordinates with other components to seamlessly monitor the multiple power supplying regulators in the system,provides the fault and reset management.When the system is connected to the I2C bus,the user can configure the system in real time by the powerful,PC-based graphical user interface(GUI),realize the system visualization and debug the system.
