Dear Sir/Madam,


As for ADUM2852E,

I will supply +5V on VISOIN, not 3.3V internal DCDC power.

Of cource, VISOOUT will be still open. And not connect this to another load.


Is this no problem or not?


If no problem, how should I think the ratings on datasheet?

The ratings have been made the reason that connect VISOOUT with VISOIN, I think.


Thanks KAOS.
