Abstract
The present invention provides an over temperature protection circuit. The over temperature protection circuit includes a reference circuit and a hysteretic comparator. The reference circuit is used for generating a reference voltage and a changeable voltage. The changeable voltage is varied by temperature. The hysteretic comparator compares the reference voltage with the changeable voltage to output a power down signal.
