5. Conclusion

There are many different temperature sensing chip manufacturers. During component selection, Intel strongly recommends that you select the temperature sensing chip with the following considerations.
  1. Select a chip with configurable ideality factor feature.
  2. Select a chip that has series resistance cancellation.
  3. Select a chip that supports Beta compensation.
  4. Select capacitors that matches the chip manufacturer's recommendations.
  5. Apply any appropriate compensation after performing a temperature profile study.

Based on the implementation consideration and evaluation results, you must optimize the temperature sensing chip in your design to achieve measurement accuracy.
