Tool/software:

Dear TI export,

   Can you explain the main purpose of IATA support? just to save energy? Or there is any other retulations for air shipment?

   As far as i know, only need to keep SOC less than 30% for air shipment.

    Hello,

    The IATA regulations are the requirements for the shipment of battery packs, where I believe the main regulation is the SOC being less then 30%. I believe their website should be used to reference their entire list of regulations for shipping.

    Regards,

    I believe the difference between the two are the thresholds since the standard shutdown mode is expected to occur at a much lower voltage. Also, the IATA Shutdown has more conditions when woken up since the packs may be checked in transport:

    I believe a charge current being passed across the SRP/SRN pins for enough time would allow for wake up.
