Abstract

A CPU voltage providing circuit has a power supply, three voltage regulation modules and a CPU. The power supply provides voltage to the three voltage regulation modules, and the three voltage regulation modules output the regulated working voltage to the CPU. The CPU voltage providing circuit also has three resettable fuses, which are respectively connected between the three voltage regulation modules and the power supply. The resettable fuses automatically shut off the voltage providing circuit under an over current condition and resume connection of the voltage providing circuit when the current is normal.
