Dear SJ -
Thanks for the post and welcome to E2E!
Sorry for your issue - here is looks like the MOSFET Q2 (CSD18543) had an issue.
Since that it is after the reverse polarity protection (Q1 of same kind of device, see attached schematic), I would…
Hi Danilo,
Here is the schematic. Unfortunately, I was not able to find the PCB layout.

I couldn't find the DOUT control register....... How can I control DOUTL and DOUTR??
What I understood…
