I want to know the details of this chip "SXE 1839" on my S17 hash board, but I can't find it anywhere.

Are you sure is that the name of the chip? I tried to search but it seems it's not yet available on the market even here https://www.zeusbtc.com/Integrated-Circuit/

Better check the chip name carefully or make a screenshot or take a pic of that chip let me check if I could find more details about that chip. Or use the link above to find it but I'm not sure if you can easily find it there since the chip name you talking about seems different.

Yes, I can confirm that the chip's surface marking is "SXE 1839".

I'm sorry, I'm Newbie now, so I can't take pic or screenshots.

 I've also seen similar on the S17Pro and T17, they're both "SXE", just with different numbers. So, I also wonder, are they the same chip?

Yea, I checked the hash board and never noticed before. I want to know what does this chip do? Is it easily damaged?

Are you talking about this part below near two capacitors?

It looks like an amplifier for the temp sensor. I couldn't find any data sheet for this chip maybe try to contact the zeusbtc below they might have an exact chip or an alternative one.

It’s a high voltage LDO.

Hi, I hope this is still helpful. We found the name of this chip is SGM2201. Currently, we find this chip on hash boards such as S17, T17, S19 hydro, etc.
