Identify circuits purpose
« on: June 20, 2021, 03:51:50 pm »
Hello. I'm trying to identify what this circuit does, but I can not wrap my head around it. The PNP MOSFET is controlling a signal (middle pin, wide trace). Is it meant for protection against inductive load?
I will be grateful for any thoughts or advice on this //Newbie :-+.

How about a schematic diagram?

That's a lot of diodes on a single track...don't trust my word cause I'm not sure, but those could be TVS diodes and zener diode to suppress ESD
