Please help me to identify this TO220-22 IC Chip for BMW TCM

So far, as I know, this TO220-22 with a symbol and 080 00005 1183 692
has quadri- open collector drivers to 4 external solenoids.

This chip is used on a transmission control module dated 1988/4 for
BMW vehicle, as image below.

I have been browsing internet for over 3 days now without any luck so
far. I can NEVER find the TO220 with 22 pin! It looks to me like a PWM
solenoid driver but just my guess. There is 23 holes on the PCB as
you may see in this picture but only has 22 pin counts on this chip.

I need to find out the pin definition and datasheet. For a quadri-
drivers, I cann't understand why they have 22pin counts? Let us prove
how usenet can enlighten people!

If anyone knows about any information, please kindly let me know.

The logo in the upper right corner is the company logo of Bosch. Your
might want to contact them:

But don't hold your breath. I have done chip projects with automotive
foundries and the stuff they do is usually highly proprietary, meaning
that it may be possible that they never release any information except
to BMW.

Whenever I reverse engineer automotive electronics, I start at the
connector and work inwards.

The 6 caps nearby would suggest 6 drivers with 3 pins per driver plus
power and ground pins (???). Look for any symmetry.

If the problem is limited to one driver, then you may be able to
substitute a single discrete driver at the rear of the heatsink.

Not even BMW will get detailed information about such proprietary
chips/hybrids.

In that case, if it is a Bosch design then the OP should be able to buy
that hybrid from Bosch. At least when I lived in Germany this company
was very good about selling spare parts. I even got motor brushes for a
1950's kitchen blender there.

You are talking about two differnt companies, this is
Bosch-Siemens-Homeappliances, a joint venture of Bosch and Siemens.
And nowadays you will be lucky to get spare parts after more than 10
years.

Not a good thing IMHO. It precludes the discovery of secondary
applications and thus potential "upside" sales.

Also not good. Once people find that out they tend to think that they
might as well buy everything at Walmart then. Why pay more if there
isn't a tangible benefit?

I assume the logic is that it avoids a lot of support costs.

Not necessarily. Just state openly that this is a specialty product with
little support. Honesty goes a long way. Lots of EEs are used to that.
For example those who must turn every penny in their BOMs and have to
rely on Asian sources. Even if you are fluent in Japanese or Chinese
support can still be hard to come by and the time zones don't exactly help.
