TPS65320D-Q1: Question about EN-Vin absolute maximum rating is 1V

Part Number: TPS65320D-Q1

Tool/software:

Hi,team

I am considering using the TPS65320D and have a question about EN.

The absolute maximum rating of EN-Vin is 1V.

Is there a possibility of damage if a voltage greater than 1V is applied for even a moment?
Even if the input voltage is a maximum of 36V and a minimum of 3.6V, will a 1V difference in voltage cause damage?

Thank you in advance for your reply.

    Hi Kawasaki-san, 

    I believe the intent of this maximum rating is that the EN source should be from the same rail as the VIN source.
    So the difference between (EN - VIN) should be ≤ 1V.
    May I know why you would be applying a different voltage to EN that is not VIN? 

    Anything beyond 1 V is not recommended and there is a possibility of damaging the device, as with all Absolute Maximum Ratings. 
    I cannot say if there is certainty that it will or will not occur, but this is why it is not recommended. 

    Best Regards, 
    Sarah

    Hi Sarah,

    Thank you for your answer.
    I understand.

    I was thinking of a way to control EN from an external source that is not Vin.
    I will reconsider.
