Protection apparatus and method for protecting electronic system using the same

摘要

A protection apparatus adapted for providing thermal protection to an electronic system includes a thermal detection module and a comparator unit. The thermal detection module is configured for outputting a first voltage signal with positive temperature coefficient characteristic and a second voltage signal with negative temperature coefficient characteristic. The comparator unit is configured for comparing the first voltage signal with the second voltage signal to generate a comparing value to determining whether or not to allow the electronic system to operate normally.
