Is it possible to use ADuM5402CRWZ for I2C communication. What will happen if I short VIB with VOC and VOB with VIC ??
Using the AduM5402 for I2C communication can have some problems. Connecting the inputs to the outputs will not provide the necessary logic to avoid latching of the input when the output goes from high to low. Read app note AN_913 to learn about the challenge of isolated I2C interfaces.
There are I2C digital isolators such as the ADum1250 designed to handle these issues and more, and they are a more compact, fully integrated solution. If you want isoPower in the same package, there is the ADM3260, which includes the function of the ADuM1250 inside a relatively small 20 lead SSOP with isoPower inside.
