We've been using the ADuM1200AR and 1201AR for a while now. They often produce a small glitch when the output side is already powered up and the input side power is ramping up or down.
I noticed the ADuM1280/1281 should be drop in replacements but they also specify an under voltage lockout threshold. Will this UVLO guarantee no glitches on power up/down if the output side is already powered up? Or does it only protect the outputs on the side that is powering up?
