www.analog.comdevices will also have some means of sensing excessive temperature, usually by means of a fixed reference voltage and a V BE-based sensor monitoring chip temperature. When the die temperature exceeds a dangerous level (above ~150°C), this can be used to shutdown the chip, by removing the drive to the pass device.
