I’m having issues identifying this part - my guess would be combined resistors or optocoupler but searching for the DABB3 or DAB83 or DA883 did not lead to much. Anybody has an idea?
I do not find anything on these markings. It is possible that they are proprietary to the board production. You might try searching for a schematic of the board if you have the manufacturer and model number of the product the board is out of. Glenda
This appears to me like a Diodes Inc. marking scheme. Three Letter/Number part ID followed by the two digit date code, and it is displayed in both orientations. That leads me to believe it may be this part: https://www.digikey.com/product-detail/en/diodes-incorporated/DMN61D9UDW-7/DMN61D9UDW-7DICT-ND/5453157
Please verify with the data sheet.

I have traced the connection on the PCB and it indeed matches the Diones Inc. MOSFET and makes sense for the circuit. Amazing, thank you!
