Build Thread- STEPPER MOTOR DRIVER

[smartgsm]

I'm loooking in internet for IC for stepepr motor driver.

For low power i use chip from Allegro A3977.

Now i need more voltage and power. For me is interesting 50 V or more and 3A per phase. And of course CLK/DIR input (not spi ...)


on internet i found this solution:

Allegro A3977

Trinamic TMC239 AND TMC401

Any other solution?

It's been a while since you made this post, but I'm wondering if you ever tried the Trinamic????
I've been trying to get one of the stepper drives, TCMC-078 or IDX-7505.
These are 7amp and 5 amp drives.

The actual motor chip TMC239 is something I would like to design around.
Unfortunately I don't have time to layout another board.
The Allegro A3986 is driving me nuts... I must get away from it.
