Hello
My DeWalt DCB107 charger is damaged, from what I have noticed, the input diodes are damaged, IC1 (IW1710-01), r15 (1kohm), r17 (0.68ohm), probably Q1 (10n60) mosfet, probably Q2 (1616) ( zener, I think 12V?) and most of all R12, because the markings on it got hot and it does not go to read the value, and I can't find a schematic for this equipment anywhere, it is between the Vsense pin and ground.
Thank you in advance for your help,
in the attachment I am adding a photo of the PCB borrowed from the MASTERGRAD website
I found a schematic diagram in the IW1710 catalog note, although it only partially overlaps, there are no optocouplers, different values of the elements.
