tda1085
Hello,
I am looking for a chip similar to TDA1085. It's closed loop and can control an Universal Motor (the one inside many domestic tools).
The question is, do you know similar chips. The problem with the TDA1085 is that it needs a tachogenerato rto close the loop, but my motor doesn't have one. It seem that it's difficult to adapt a toothweel and an optocoupler as a simple digital tacho generator, it needs an AC analog one.
I know jet...
UC3637 (is not valid because it is for DC motors).
U208B (could be, but it's difficult to find).
I would be also interested in real circuits with the TDA1085, because the datasheet has many empty values for resistors.
Thank you.
