Question from my customer-
We’ve started testing the ISO7041 on some newer designs, mostly due to its low supply current. Normally we use a ADI part.
One of the issues with the AD parts is they sometimes glitch as the power supply on the output side is ramping up (usually while it’s below I think 2V or so).
I see in the datasheet for the ISO7041 that the output is undetermined when the output supply is <1.54V and that the tPU (Time from UVLO to valid output data) is 1-5ms. Does this mean that the output is undetermined for 1-5ms after the supply is >1.54V? Or does it mean the output is defined high (for the non-“F” version) after 1.54V and then takes the correct state (based on the input side) 1-5ms later?
Basically what I’d like to know is: can I remove the circuit we use to filter the AD glitches if we use this TI part or should I leave it in?
