advanced version of their phase-control motor controller chip.
BTW, Mitel bought GEC Plessey, then I think Zarlink bought the
line, and has now discontinued it... Anyway, you're in luck,
ON Semi still makes the TDA1085 in the C version (442 in stock
at DigiKey, for only $1.68 each). I have Motorola's TDA1085A
and TDA1085C datasheets, if that's of any help. The Plessey
5-page TDA1085C datasheet has a very detailed but very hard-
to-understand schematic, while the 12-page ON Semi datasheet
has a detailed "block diagram" schematic that looks useful.
The TDA1085 looks like a pretty useful chip. Anyone?
You may remember that Motorola's linear ICs went to ON Semi,
and the rest of their ICs just went to Freescale. < sigh >

the drawing may have all the necessary elements, conveniently
pared down to the essentials, it's so badly drawn as to be
nearly useless. The voltages, currents and signals are not
arranged top to bottom, up to down or any other sensible way,
except to say, "Where's the nearest edge?" to make landfall
for a package pinout location. Anyone seeking to design with
this IC will have to completely redraw the schematic before
getting underway. I do believe that poor documentation like
this can help to spell the death knell for a chip.

Sadly, it doesn't look so useful at a second glance. While... The Plessey 5-page TDA1085C datasheet has a very
