MICROELECTRONIC DEVICE EQUIPPED WITH A THERMAL PROTECTION CIRCUIT AND THERMAL PROTECTION METHOD FOR A MICROELECTRONIC DEVICE

摘要

A microelectronic device includes a first circuit and a second circuit, coupled to the first circuit for selectively preventing operation of the first circuit when a device temperature is higher than a temperature threshold. The second circuit is provided with a temperature responsive element, thermally coupled to the first circuit for providing a shutdown signal correlated to the device temperature. The temperature responsive element includes a reverse-biased junction element and the shutdown signal is correlated to a reverse leakage current of the reverse-biased junction element.
