I was thinking of those with stock to use up on a well designed board. I.e decent optos as you indicated earlier.
Perhaps I mis-read things but my interpretation of articles elsewhere on such matters suggest it is desirable to synchronise the currents for all drives in a system. Obviously this becomes academic if it isn't possible to slave the oscillator of one TB6564AHQ/THB6064AH to another. I was thinking of the synchronisation to be in a broadly similar manner to that shown for the multiple L297s in Fig 3 of http://www.st.com/internet/com/TECHN...CD00000063.pdf accepting that a L297/L298 combo has far more crude current control.Originally Posted by lucas
