Hello,
I’m developing a stepper motor controller by using STSPIN220. I’ve designed the schematic and proceed to PCB layout.
It should be compact as possible and won’t work rapidly. So, it won’t heat that much.
I have several questions.
1- Are Ref(P11) and Toff(P12) layouts correct ? Should I follow different(much correct/better/optimized) layout ?
2- Should I make differential pair for output pins(A1-P3, A2-P5, B1-P10, B2-P8) ? If differential pair is necessary, should I do it for A and B pins too ? (So, all A and B pins will have the same length)
3- If you have further suggestions, please indicate.
EDA:
KiCAD v8
