    Hi , 
    

    Could you please let me know the power-up sequence when using LTC6820  in a multidrop configuration?
    

    I am worried if the slave-nodeis not powered the voltage on IP and IM will not meet the Absolute maximum rating when the master-node is powered and the slave-node is not powered on. And is the same the other way too.
    

    

    Thanking you 
    

    With best regards
