Team,
my customer is using LMR33620 in a new application. There is a possible fault condition where the Vin of LMR33620 is not present, but the EN signal (3.3V) is still present.
That means the LMR33620 is unpowered and EN is 3.3V.
- Is this allowed?
- Are there any side effects expected?
They have done current measurements and it seems like there is no increased current going into EN pin.
Thanks
