Hi team,

we want to check how to connect the GND and PGND. how about connecting the GND with the red circuit, and PGND with red squar? Thanks.

Hello Frank,

You are correct except for the following recommendation.

I would connect the lower resistors on LINEOV and LINEUV to GND.

Then pin 8 (GND) connects directly to pin 13 (PGND) as described in section 11.1 of the UCC2897A data sheet

Regards

John
