i build two circuit l297 unipolar with IRL3705N.(pMinMo.com)
but with little changes.
I did very small changes because putting all mosfets in a row (for heatsink).
they work perfect when one of them is running and the other is stoped.
but when i start both of them in a same time with one power supply(32v 6A , step motor 3.7A,2.5V)they have distortion on each other.
i mean when a single driver works no problem
But when two of them works with a comon power supply, I have a problem.
What do you think?
