ABSTRACT
As the technology and information developing fast, the power source management technology is more and more important in the 21st century statuses. Whether it is in 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 based on the most popular power source of monolithic processor systems which was ±5V、9V、12V. and tunable LCD bias power source (- 10V - 24V). Its periphery electric circuit was designed by the power chip MAX715, and with the AT89C51 and pressed key to carry out purpose of power source management system.
The hardware of this topic was designed by Protel99 SE ,and the hardware emulator was designed by base Keil c V3.60.When the system was debugged, it carried out all required precision.
Keywords: Power Source Management；Voltage Regulation；MAX715；Alarm
