TMC239/249 HV schematics

[mikefu]

Hello,

I'll develop a new microstepper drive with TMC249 on High voltage, 80VDC, 4A; On your Application note(TMC239/249 HV schematics) i'll found more information about it but the chematic appear incomplete on the last page.
Where i can find the integral document?

Thenk you for reply.

For a 80V high voltage driver, it is best you refer to the schematics printed in the data sheet, using N-channel transistor bridge only. The TMC249 HVHR board schematics is for reduced voltage with about 58V max., since P channel transistors above are hardly available. The other high voltage driver schematics on the web is similar, but not as up-to-date.
Please also refer to the FAQ manual.
