Take a look at this example of an IC found on a circuit board:


JL branded ic


Brand is found on many PCB's of Chinese/India manufacturers of different kind of devices, mostly consumer based.

For example, there are many printed logo's on IC's listed on this site, however you cannot find this JL (or sort of italic pi?) logo, unable to find it anywhere. Also when this logo is on an IC and searching for the part-number/IC model number, always lead to a dead end, I am never able to find a datasheet.

So what is this misterious brand, is it actually a brand, what's the origin and actual name of the manufacturer? And is the part-number/IC model number really a description of what it is or just a random number?

    \$\begingroup\$ @Sparky You meant "accepted", not "favorite" (this is another, unrelated, feature of SE). Anyway, the "closed" state and "has an accepted answer" are completely unrelated. Even if OP has accepted an answer, if the question is on-topic, it doesn't have to be closed. Anyone else should be able to add another (possibly even better) answer. So, yes, if enough people consider this is on-topic, the status has to change. \$\endgroup\$ – dim Apr 11 '18 at 16:57

I remember this logo. Don't ask me where I know it from. A bit digging showed that we had a similar request for this chip already:

Help for identifying pinout of unknown mp3 chip

Manufacturer is probably called "Jerry" or "Jay Management". Probably there simply is no english name for the manufacturer.

Maybe some Chinese speaking member can chime in and use some Chinese search engine fu to find out more.

  • \$\begingroup\$ Found out it is a mirrored pi sign. I isolated the logo and drop into google and google showed me a pi sign that looks very similar. Also scan it with OCR software online but nothing. \$\endgroup\$ – Codebeat Apr 11 '18 at 20:18
