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.
