Hi,
I did the power check and everything looks fine when hooked to the car : a beautiful and steady 3,35V at check pads and at RN52 pins !  When powered with my arduino uno board, tension was not over 2,8V, explaining the cut after a short while...
I decided to keep it hooked and drive to work (45 min trip) : everything worked flawlessly, including reconnection after a short stop. I'm happy but don't understand anything. I suspect a dry soldering somewhere but on my trip I went on a very bumpy road and no failure occured.
Actually, it was a module I sold to someone who reported the failure and when I got it back for replacement, it refused to start in my car, kind of confirmation that it was faulty. Without time to look closer at it, I left it on my desk's corner and eventually came back to it recently. Now it works without any fixing unless the software update and factory reset previously performed.

I'll retrofit it and my v4.2 with the THS4522 v1.2 AMP...
Anyway, thanks Seth for your answers !
