hello, I'm using ISO1I811TXUMA1. Does this IC need an isolated supply or a mains supply to supply it? If an isolated supply is required, how can we provide it?

Hello,

Thank You for posting your query in the Infineon community.

I hope your query is regarding supply isolation between input & output side of the IC.

Yes, input & output power supplies to the IC should be isolated, please refer the below link for more details,

Hello,

The primary application of ISO1I811TXUMA1 is to provide isolation between input & output. If we use common power supply without isolation, then the galvanic isolation provided by chip would be broken.

Please share information about your application for better understanding.
