Morning all!
This is from a air blend motor from a BMW.
The chip is not a package I have ever seen before and I cannot find a datasheet for it either.
Does anyone have any details or insight?
Thanks,

Why couldn't it be just a BGA package soldered into the custom assembly?
Typical mass-market automotive sub-assembly engineered to the nth degree.
Quite typical to see a completely custom semiconductor
or maybe a selected commodity part, but with a proprietary internal "house-number"
It may be a custom package, but then it may be a standard power BGA package.
Can you take the dimensions of the package and research that?
Here are some photos with a scale (mm).
I have also removed the chip from the housing to see if there was anything on the underside, sadly not.
You're probably right in that it's something completely benign in a custom case.
In this case something like a brushless motor controller IC.
Motorola SC512502YTM is listed as "specialized hot IC" at various Hong Kong based parts suppliers.
If it’s broken, you can try and order one of those and see if it fixes your problem. If you are curious about what it actually does you might have to ask Motorola for a spec-/datasheet.
What year BMW are we talking about?
Does Motorola still own any semiconductor divisions? They've sold them all off, I think.
So I need to find out what temp sensor this is..
My guess is a KTY82/210.
Can anyone confirm that, or am I just wrong?
Can anyone ID this IC, please?
I got it from a canon digital camera powered by two AA cells and seems to control a mosfet for the boost/dc-dc for the xenon flash tube. I could see four control lines but shorting them to ground or supply (with various combinations) and nothing seems to happen. I would like to make it work to play with
Googling for the numbers did not turn up anything useful. Flash control IC turns out mostly LED drivers for mobile phone flash.

Well unless I'm mistaken they are the same as this part. In which case they are varicaps/varactor diodes.
In a way these came to me the same as you. My father in law was an old time electronics guy(Air Force in the 60's an he was also a Ham). When he passed I inherited all of his collection of "stuff".
Hello everyone,
Not sure if I am posting correctly as I have never used a forum before but here goes
In any case I have a question about a strange component I am trying to identify. I am in no way an engineer but I do enjoy all electronics.
Can you help?

From context and markings on chip and board, it's obviously a bridge rectifier in a DIP package.
I'm trying to identify the two female sockets on this PCB so I can find mating male connectors (so I can build my own module). This is from a GRiD 1520 Laptop computer and was made in 1988. The connectors are 0.05" / 1.27mm pitch (measured), the short one is 40 pins, the long one is 60 pins. These are used as a small form-factor PC-AT 16-bit ISA bus to allow expansion modules to be plugged into the laptop (a 268 compatible).
Hours of searching has lead me to nothing. I cannot even find a photo of any of the alleged modules that were made for this laptop, other than a small part of a diagram from an advertisement from back in the day.
The only markings I can find on either connector (aside from the bottom which I cannot see without desoldering the connector) is the number "8111" followed by a triangle (see photos). The 60-pin connector has the number 8037 and the same triangle symbol. I don't know if those are batch numbers or related to the part number, or if the triangle is a pin-1 reference or a manufacturer mark.
If anyone can identify these, I would greatly appreciate it.
Thanks,
Matthew
Those look like card edge connectors to me, which would explain the lack of male connectors for it. The male connector would be the edge of a PCB with contacts on it.
Yes, looks like card edge connectors. The C64 uses
this one for the user port. In the datasheet is the recommended footprint for the daughter cards. The standard 1.6 mm PCB thickness works well for it.
Those are bog-standard PC board edge-connectors.
When you design your module, simply include the matching "fingers" on the end of the PC board.
They are typically gold-plated for reliabilty.
I considered the same thing (card edge), but these points make the think it has a mate:
* If it is a card edge, the offset nature of the connectors would make a very strange configuration for the module plugging into it. Staggered PCBs seems a little odd.
* At around 5:20 in this video the engineer takes a module out of the system, and although he never shows the interface end directly, you can see (briefly) there is a connector vs a card edge:
* These laptops are really well made and having a card-edge connector for an external devices does not fix with the design of the system.
* The Ethernet module manual shows what looks like connectors. Unfortunately it is all line drawings and there is no actual photo of the module.
* Some advertising for the 1500 Series shows a drawing of a module that looks like there are connectors.
The mating connector may be similar to the Hirose FX2 series.
I looked that that, but the FX2 is D-shaped. It is too bad the HiRose website is awful for searching! I wonder if they ever heard of taking nice photos of their products?
* If it is a card edge, the offset nature of the connectors would make a very strange configuration for the module plugging into it. Staggered PCBs seems a little odd.
Your own pictures/drawings say that strange or not, the connectors are both used in an offset configuration for the ethernet cartridge. The PCB's don't have to be staggered, just the connectors.
* At around 5:20 in this video the engineer takes a module out of the system, and although he never shows the interface end directly, you can see (briefly) there is a connector vs a card edge:
The SCSI cartridge in the video appears to only use one of the connectors. I guess that's the nature of general-purpose expansion connectors.
* These laptops are really well made and having a card-edge connector for an external devices does not fix with the design of the system.
Let's flip that question. What would appropriate connectors for this design look like for an end-user quick-release future-expansion cartridge interface? We already know the answer isn't any kind of header pin arrangement.
* The Ethernet module manual shows what looks like connectors. Unfortunately it is all line drawings and there is no actual photo of the module.
* Some advertising for the 1500 Series shows a drawing of a module that looks like there are connectors.
You have a point. Perhaps some sort of right-angle panel-mount fingerboard connector was available back then? Unless you obtain good pictures of one of those unobtainium modules, you may never know. It's possible many of them only existed as prototypes and never made it to market.
Nonetheless, it doesn't change what it looks like. Odds are you can use a PCB for your interface to those connectors. You should be able to confirm that easily enough with simple experiments. Alternately, you could replace "Denny's" board entirely and interface to the easily-mated pin headers and do whatever you want if you need the quick-release feature.
So I have a confirmation from someone who has seen one of the mystery modules, and they said it has a connector. They also said they have tried to identify the connectors and could not. I am trying to find an actual photo of one though. The modules were produced in some quantity, they were not just prototypes, so they are out there somewhere.
Going ahead and using a PCB is possible, but I think it would be problematic since the thickness would have to be 2mm / 0.078", which is pretty think and not a "standard" 2 or 4 layer PCB.
Yup, I could also make my own backplane, and that is starting to look like more of a reasonable possibility, especially since I have managed to identify the lower connectors which are this series from AMP:
https://www.te.com/usa-en/product-5-103911-2.htmlBe that as it may, I would still like to identify the upper connectors in question.
Found it! 3M-PAK50 Series, specifically:
Socket 40 pin: P51-040S-S1-EA
Socket 60 pin: P51-060S-S1-EA
Plug 40 pin, right angle: P51-040P-SR1-EA
Plug 60 pin, right angle: P51-060P-SR1-EA
Of course, almost impossible to find in stock anywhere. I think making a new version of the backplane will be more cost effective. But, at least I know what the connector is in case I want to be a purist. ;-)
Thanks everyone for the help.
