Hi Smruti,

Thanks for the post!

The IC303 is a Digital Isolator IC (Si866x). It isolates data paths.

This eval board is connected to PC via Micro USB connector (X302C) which has ground connection named 'ISOGND' and 'PGND' from battery or Aux supply. To provide the isolation and avoid ground conflict this digital isolator is used.

Hope this clarifies your doubt.

Feel free to post your queries.

Thanking you!
