TPS659037: Using a supervisory circuit with TPS659037 when used on AM571x Development Kit for proper power down sequences with sudden power loss

Hi,

When using a supervisory circuit to initiate the power down sequence of the TPS6590379 should it be connected to reset pin (K9) or the enable pin (J5)?   I want to ensure the proper shutdown of the PMIC (and the attached AM57xx processor) in the event of sudden power loss.  

Thank you,

HSG

    HSG,

    Hi, nice to talk to you again. I recommend using RESET_IN (K9) for the input on whether the system should shutdown in this condition.

    Thanks,
