TCAN1146-Q1: Is Isup related to temperature or humidity?

Part Number: TCAN1146-Q1

Dear team,

Under sleep mode(VCC=VIO=0V) , is Isup related to temperature or humidity? Which factor has the larger impact, temp or humidity? Do we have the related test report?

Thanks & Best Regards,

Sherry

    Sherry,

    For all electrical characteristics, the min, typ, and max consider the full temperature range. We guarantee our electrical characteristics across recommended conditions, the test conditions in that specific parameter, and across temperature unless stated otherwise. Temperature is going to have the most bearing for these electrical parameters, as humidity is not something we measure or vary when we validate these parameters.

    Please let me know if you have any other questions.

    Regards,

    Hi Eric,

    Thanks for your reply!

    I noticed that almost all datasheet won't include humidity as a test variable. Is it because humidity has no impact for electrical characteristics?

    Thanks & Best Regards,

    Sherry,

    The only thing related to humidity that I can think we monitor is moisture sensitivity level, and you find more information about that here.

    The effect of humidity would seem to be a mixture of temperature and moisture, both of which are defined by our datasheet and quality guidelines. Humidity itself could affect a circuit through temperature change and increased moisture or either one separately. I'm not familiar with humidity tests or regulations for ICs, so I can't give a detailed answer on that.

    Regards,
