ADP5073 EN pin voltage

smurfen on May 12, 2020

I can't find the maximum operating voltage on the ADP5073's EN pin in the datasheet. I see that the absolute maximum voltage is +6 V but what is the operating maximum voltage?

Hi Jonas,

Technically that is the MAX operating voltage: 6V and not exceed it to avoid damage. On page 3 of datasheet under Precision Enabling, you can find 1.15V High Level Threshold. Converter will start…

Hi Jonas,

EN max operating voltage should be 5.5V.

Hi Fil

So what is the OPERATIONAL maximum voltage? In the datasheet you write Stresses at or above those listed under Absolute Maximum Ratings may cause permanent damage to the product. This is a stress rating only; functional operation of the product at these or any other conditions above those indicated in the operational section of this specification is not implied.

Hi Jonas,

For me, it should be ok to have EN signal that is lower than 6V to have margin. Let me confirm with designer and get back to you once I get the answer.
