Thanks for the great info David. I can get TEA3717
(I think Allegro but haven't seen the chips)
reasonably cheap, and have considered using them for
some small size 17 steppers at about 350mA.

Being the expert with these, do you feel they're
ok for 350mA from a 12-16v source for very
constant use? And will they need heatsinking,
ie what temp rise to expect? :o)
