I have a question ADP2442 EN pin.
If ADP2442 is not power supplied , the voltage is impressed on a EN terminal, is it a problem?Would there be a damaged possibility?
The ADP2442 will not be damaged as long as you do "not exceed" the absolute maximum rating of the EN pin (-0.3V to 40V). Impressing a voltage on EN pin while there is no input voltage present is not a problem.
Thanks for your interest on ADI products.
Thank you for your quick answer.
