Do You know another Chip-Like housings stepper Driver which can provide 5-6 Amps on each output?

Regards,

this assumes too much.
5-6 amps is very high, typically in the range of metal cutting mini-milling machines.

most unitary chips are less than half of that.
in this power range, most of the drives are using individual MOSFETs and a driver chip.

the correct way for selecting things is to start with what has to be moved.
then figure out the power needed,
then a gearing needed for speed

then determine how to get that power from a motor. either high voltage and lower amps or higher amps and lower voltage.

There aren't any.

You will need a high power stepper driver such as the products from Gecko or Leadshine.

Try a parametric search on your favorite electronics supplier.

Looks like DigiKey has one choice in stock that can handle 8A at 9 to 60V. They are only $40.98 each.

Interesting chip, but it is just an H-bridge, not a full featured stepper driver.

The Step&Direction microstepping driver chips they have only go up to 2.8A like this one:

I don't know if you could parallel them to get 5.6A. I would expect not since missing a step would have the output drivers fighting each other.

This is the answer.
the option is to buy a packaged driver like leadshine or gecko, or old stuff from e-bay.
for this much power, a project will have some use, spending the $50 or $150 per axis on a driver is a smart move and eliminates headaches.
but this much power is really in the small commercial metal cutting world. a 10 ft x 5 ft plasma or router table will not need this much power. Power costs money. how much power can you afford ?

If you needed to build something like this yourself you'd start with something like a TMC262. The TMC262 would handle all the current limiting, microstepping sequence, gate driving, etc. The remaining "exotic" parts would be the eight mosfets and current sense resistors.
