Part Number: AM26LV32E

Hi team,

My customer found H level voltage occurred in Vo and Vi(+) pins during power supply shutdown, it was a 100ns pulse.

Could you please let me know if it is a expected behavior? if not, what could be the reason?

HI Zeming,

Do you have a schematic and/or scope shots of the event?

I'd like to see if there is anything that could possibly be holding charge during a power down - this doesn't sound like expected behavior - but it isn't something that I have really have seen before either - so any additional information on the system and test setup would be great so I can help look into the issue a bit deeper for you!

Best,
