Welcome to theTechnical Forum. I am sorry. I have tried multiple ways to verify what the part number is . I am unable to find anything with the part marking shown. Though I am not sure I am looking at the correct part. Which part do you need us to look at? I am just confirming that I am looking at the correct one.

its the one that has A DBZ its a 10 pin IC i think its somthing to do with the power distribution.
Thanks

4

the info on the IC looks like AtDBZ but the t is something like a symbol in Japanese or China.

5

and on the other one it has AtDYD

I am sorry. I have looked all over. I am unable to verify these part markings.

Hi, it’s an E-Fuse for powerline applications, similar to the STEF4S. You can look up the STEF4S datasheet online to check the pin configuration. It’s an electronic fuse that controls the current usage on a board.

Just a heads-up: it monitors for short circuits and will disconnect the powerline if the current rises too high. However, after such an event, you might want to check for potential leakage issues.
