I did one for California Micro Devices a number of years ago that
could handle a 4-cell stack, with individual charge and discharge
control.

I'd post the schematic but it's E-size ;-)

Individual current (plus voltage/temperature?) measurement and
control for each cell? Nice.

We can handle E size.

My comment re TI's tps65800 stemmed from the mass of different
kinds of items in the IC, and the quantity of each. Impressive.
Another thing that's impressive, or I should say, intimidating,
is the mass of digital setup and control registers and bits in
the tps65800. You'd need procedures, checklists and committees
of other engineers poring over your design to be sure you didn't
forget a bit here, or enter the wrong value there. You'd need a
mass of test procedures to evaluate the result, sheesh!

I'll see if I can resurrect it into something readable. It's so old
it's in OrCAD SDT III format ;-) I'm not sure if I still have that
executable. I may be able to convert it to MicroSim format.

Hello Jim,

It should load fine into a newer OrCAD version. I used SDT III for a
long time and clients never had issues with that.

That is indeed a cool chip but it does come with a hefty sticker price,
$6.50/1k. It seems a bit high for the target markets mentioned in the
data sheet, like portable media players. 3G handsets, maybe, but long
term they'll have to give those away with the usual $50/mo 2-year contracts.

I got out some SDT files and tried it with Capture v7.20, and they
worked.

Now all I have to do is find the archive ;-)

Hello Jim,

I got out some SDT files and tried it with Capture v7.20, and they
worked.

There just isn't much backward compatibility which always irked me with
OrCad. I think with Cadsoft Eagle it might be similar but they don't
switch versions so often.

Now all I have to do is find the archive ;-)

Oh boy. IIRC these old SDT files contained text in the title block in
one consecutive string each. So if you remember the title a disk parser
might be able to find the file. Shouldn't take too much search time
because you can limit that search to schematic files.

I found the invoice files ;-)

I think the schematics may be in the storage facility I rent.
