EN6337QA Datasheet clarification on absolute max rating of POK pin

[TM_00]

Hi Mostafa,

I have a question regarding the absolute max of the POK pin.

Datasheet states that it is an open drain.

It also states that it cannot reach more that VIn+0.3V.

If we have an application with EN6337_Vin=2.5V and a 3.3V microcontroller, it looks odd that we cannot supply the open drain with 3.3V ?

If it is really an open drain, I would guess a maximum of 7V on the POK open drain, but it's not what is written... can you explain why ?

Thanks a lot,

Thierry

Hi Thierry,

Yes, you can pull up POK to 3.3V without any problem when your input is 2.5V.
