Re: TMC5160 substitute?

Robert Benward

Thank you!  That makes perfect sense now.  Looking at them again, yes they look  like protection diodes and not MOSFETs.   So, you don't need the bottom board for our purposes.

I wonder why Trinamic obsoleted them (the TMC5161).  

I also realized the basic TMC5160 is a 60V chip, it must be the MOSFETs that limit them to 35V.  The QHV5160 must be using higher voltage MOSFETS
