  • System and method for processor dual voltage detection and over stress protection
    Patent number: 6327663
    Abstract: Method and system for preventing electronic overstress during powering up a processor with voltage detection capabilities employing a mechanism for detecting the voltage requirements of the processor to be coupled into a motherboard and accordingly adjusts the power supply of the motherboard to the processor voltage requirements. The detection mechanism includes sensing of logic signals by sensing a voltage from one or more pins of the processor. Those pins are internally connected to ground or internally not connected thus facilitating sensing of logic signals prior to powering up the processor. The probed signals are used to control the power supplied to the processor by adjustment mechanisms applied to power regulator or programmable logic devices.
