摘要
 随着信息时代的来临，电源管理技术在21世纪中的地位越来越重要。不论是最先进的个人电脑、便携式无线通讯设备，还是汽车电子产品，能否实现高效、智能的电源管理，将对其整个系统的性能产生巨大的影响。新技术、新功能能否成为现实,也取决于是否能够实现高效、智能的电源管理。
 本课题设计的基于PIC12C5系列单片机的通用电源管理系统，针对各种常用单片机系统所需的工作电源±5V、9V~12V、可调的LCD偏置（-10V~24V）电源， 实现基于MAX715电池供电系统通过PIC12C程控满足上述需求,在欠压时给出报警提示。
 此电源管理系统由PIC12C508型单片机、MAX715及其外围电路、控制按键和简单的低压报警电路组成。本课题首先对MAX715电源管理系统电路原理和性能进行分析；其次对基于PIC12C5系列单片机的通用电源管理系统进行硬件和软件设计；最后进行系统调试。

ABSTRACT
 Along with information time approaching, the power source management technology is more and more important in the 21st century statuses. Whether is the most advanced personal computer, portable wireless communications equipment, or automotive electronic products, can achieve high efficiency, Intelligent power management, its performance throughout the system have a tremendous impact. New technologies and new functions can become a reality, but also on whether it is possible to achieve highly efficient and intelligent power management.
 This topic was the general power source management system which design was based on the PIC12C5 series monolithic. Its design aimed at each kind of popular monolithic processor systems which need work power source ±5V、9V-12V, and tunable LCD bias power source (- 10V - 24V). It came through the PIC12C monolithic which controlled the MAX715 battery power supply system, satisfied the above request, reported to the police the prompt with low voltage.
 The power source management system was composed by the PIC12C508 monolithic, MAX715 and its the periphery electric circuit, the pressed key for control and the simple low pressure alarm circuit. This topic first carried on the analysis to the MAX715 power source management system circuitry and the performance; next carried on the hardware and the software design based on the PIC12C5 series monolithic general power source management system; finally carried on the system debugging.
