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!
You are welcome! Glad to hear it will work.
