Dear Expert

We found that thermal test is unstable ,but after initialization the thermal is nomal . So we add a only initial succeed then we could read thermal ,and these abnormal temperature phenomenon disappeared .

But there are many times for the ability to make the thermal test to be normal  Is there any way to optimize it ?

    Hello Gabriel,

    I am not sure I am understanding your question. Are you testing the temperature accuracy of the TS2 pin reading? 

    It is not recommended to use TS2 pin as a thermistor. This will prevent the device from entering shutdown mode. There are multiple external pins that can be configured as a thermistor. The TS2 pin is mostly used for wake up.
