Is this IC ADM803/ADM809/ADM810?

Fri Apr 06, 2018 8:08 am

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(datasheet: http://www.kynix.com/uploadfiles/pdf/ADM803LAKSZ-REEL7.pdf) which is same package but unfortunately pinouts doesn't match.
