    I'm looking for the cheapest available Temperature Sensor IC.

    The application is to detect any abnormal heating in the circuit casing
    and in this case turn self off.

    So accuracy etc. is not needed.

    Any advise will be greatfully registered.

    A thermistor or a thermal fuse are likely to be cheaper than a
    temperature-sensing IC.

  5. plus the circuitry to make some use of it....

    Mike really needs to write a longer description f the problem and the
    function of the solution he wants.

    my finger can sense temperature, but it wouldn't be much use without a
    brain to act on the fact.
