I'm trying to find out what this IC is and appreciate any help! It is located inside an EV charging cable and its main task from plugs datasheet is:
"STATIC RESISTANCE (FROM PROX. DETECTION TO GROUND) 150ohm RESISTANCE WILL INCREASE TO 480ohm WHEN LATCH IS DEPRESSED" (No more info on datasheet about this mini circuit)
Here is the reverse-engineered schematics of the small pcb in the charging plug:
I guessed it might have been ADM803/ADM809/ADM810 which is same package but unfortunately pinouts doesnt match.
