Hi,Partners.
What does Parameter-Not operational lifetime meaning? Is that storage temperature?What's the difference between normal operating and Not operational.Thanks.
Solved! Go to Solution.

Hi @A-maX,
Presently we don't have the thermal resistance value provided in the datasheet of TLE 4959-U. We have contacted our internal team to get the thermal resistance values.
You could also consider the TLE4998 Datasheet as a reference for thermal resistance and junction temperature calculation.
Thanks,

Hi @A-maX,
Ques: What does Parameter-Not operational lifetime meaning?
Not operational lifetime - When the sensor is not powered or not operating.
Ques: What's the difference between normal operating and Not operational
When the device is powered and operational, the temperature range for normal operation is provided. In Not operational lifetime temperature range is provided when the device is not powered.
Thanks,

Hi,Krupashankar:
Thanks for your response,as TLE4959-5U 's operating temperature range is -40 to 175°,max can reach 185°,but in Not operational lifetime temperature range is -40 to 150°,Why is the temperature range even narrower when the device is not working?

Hi @A-maX,
The operating temperature range is the junction temperature of the device as the device may heat up during the operation, Not operational temperature is the surrounding temperature when the device is not powered so the operating range is higher than the not operational temperature.
