can you give me some help ?
First I want to point out that we have a video on how and why the levels on the ADuM1250 work here:
How I2C Isolators Work
So with the ADuM1250, the levels on Side1 and Side2 are different.…
So with the ADuM1250, the levels on Side1 and Side2 are different. Side2 is I2C compliant and Side1 is I2C compatible. Side 1 must interface with compliant devices. Communication isn't possible between devices that both have a high Vol.
Before doing a respin on the board, its possible mechanically to face the ADuM1250 in the other direction. If the ADuM1250 is turned over dead-bug, and the leads bent backwards, it can be soldered down. Does this help with the debugging?
