 Hello guys.

 One of my customers is considering using TMP112. They'd like to get advice or suggestion for the following queston to detect if TMP112 is broken as much as possible.

Could you please tell me your advice or suggestion as a reference for them?

Q:   What is the most likely phenomenon when TMP112 is broken?

 Your reply would be much appreciated.

 Best regards,

    Hello Kazuka,

    TMP112 may be "broken", if the device is operated beyond the recommended operating conditions for long duration. Also it depends on how much the excursion above the recommended operating condition is the device is exposed to.

    Hello Amit,
    Thank you for the prompt reply.
    Your reply is helpful for the customer and me for their circuit/PCB design and manufacturing .

    But I'm very sorry my question I sent previous was too short to understand.
    I meaned the device broken is spontaneous failure due to aging.
    For instance, if HDC2010 is broken in a spontaneous failure after 5~10 years using, what is the most likely phenomenon then?
    Would the phenomenon be read temperature I2C data become the minimum code? Or maximum code?

    Your reply would be much appreciated.

    Thank you again and best regards,
    Kazuya Nakai

    Hello Kazuya,

    That would be rather very open ended. Their could be some form of mechanical failure of the device, electrical overstress, that may lead to temp accuracy being out of bound or the device not responding to I2C commands. Unless there is a specific concern here due to operating conditions for the end application, it is very difficult to state anything.

    Hello Amit,

    Thank you for your reply. Your comments are helpful for my customer and me.
    I understood that it is difficult to say which most likely is without specific conditions.

    Thank you and best regards,
