Hi there,
Is anyone familiar with a 8 port surface mount chip that has SM858 YD5REAL written on it? I can't find this in any online database.
I recently had a phone charger stop working after I dropped it off a balcony, so I've been probing around with the circuit to see what got disconnected.
There are two boards that comprise the unit. One takes the power from the wall, and the other seemingly distributes it via usb ports. There are two wires that connect the two boards, which appear to originate out of the transformer.
The first board is receiving power no problem, but the second isn't.
There is a small surface mount chip in the center of the first board that has the part number listed above. All eight pins are at ground potential when probed, so I think it might be part of the problem.
Thanks,
Corwin
