LMP92066: Recommend operating coditions for pressure

Masanori Tachibana
Genius 5350 points
Part Number: LMP92066

Hello support team,

I have a question regarding LMP92066.

Our customer might use this IC under low temperature and reduced pressure environment.
Although recommended operating condition for ambient temperature is specified in datasheet, are there any recommended operating condition for barometric pressure as an IC?
If you have such data, please let us know.

The conditions assumed by the customer are as follows.
Balometric pressure: about 500 hPa
Temperature: -20 ° C (minimum)

Sincerely,
M. Tachibana

    Hi Tachibana-san,

    I am unaware of any specified pressure limits for our devices.  I will reach out to our quality team to see if they have any information.

    Thanks,
    Paul

    Hi Paul-san,

    Thank you for the reply.
    I guess that there is no data on the recommended conditions for the atmospheric pressure, but it would be helpful if you have any information.

    Sincerely,
    M. Tachibana

    Hi Tachibana-san,

    I have confirmed with our qualification team that we do not do any low-pressure testing.  We do use autoclave characterization, which tests the devices at about 2ATM of pressure.  Low pressure applications may need higher qualification levels, such as space qualification.

    Our quality team recommends testing the design under these conditions to verify their functionality.

    Thanks,
    Paul

    Hello Paul-san,

    Thank you for confirming your qualification team.
    I understood that you didn't have the testing data that is under low pressure environment.
    We will recommend the customer to evaluate low pressure environmental testing throughout the equipment.

    Sincerely,
    M. Tachibana
