Part Number: TMP116

Dear TI:

About TMP116  i have some questions,  i know tmp116  is I 2C- and SMBus-interface compatible, has programmable alert functionality,

1. When the TMP116 temperature sensor fails, which mechanism can be used to judge it? (such as other sensors with CRC, or status word to determine the sensor failure).

2. For example, if the sensor power line is not connected properly, the AD value collected by the sensor is 0. At this time, how to judge whether the AD value is normal or abnormal?
thanks a lot.

  • Hi user,

    If the power line is not connected, the sensor will not ACK. Most controllers will halt communication and report an error in this situation. If the controller continues to attempt read back, it will receive 0xFFFF, because the bus idles at logic high.

    Thanks,
    Ren
