I have an application using the ADuM3160 where the customer wants to be able to dynamically select between lo-speed and full-speed mode. The datasheet says that the part cannot make this adjustment on the fly so I added provision to cycle power on both sides of the isolator.
Are there any power sequencing requirements for Vbus1 and Vbus2?
What are the timing requirements for the SPD/SPU pins being set with respect to their power rails coming up?
Thanks,
Matt
