Method and apparatus for thermal protection in an integrated circuit

Abstract

Some embodiments discussed relate to an apparatus comprising a temperature sensor disposed in an integrated circuit, the temperature sensor including a bipolar transistor having a collector coupled to a portion of a substrate of the integrated circuit, and a bandgap reference circuit configured to generate a reference voltage, and a comparator coupled to the temperature sensor and the bandgap reference circuit, the comparator configured to receive a first voltage from the emitter of the bipolar transistor and the reference voltage from the bandgap reference circuit and generate a switch-off signal based on a voltage difference between the first voltage and the reference voltage.
