This is a really old thread, but I am just catching up on my email and
wanted to add my 2c, for the record:
The one advantage of L297/L298 solution is that you can chain
several L298
chips in parallel. You can't do that with an LMD18245. Yes, the PCB
routing
gets hairy pretty quickly, but it can be done, and it works. I am
currently
using boards utilizing that very method - 3 L298 chips in parallel
per axis
driving stepper motors with 5A per axis (
).
Of course, one could argue that if higher currents are needed, one
should
just go with discreet FETs anyway, and I wholeheartedly agree, but
that's a
different topic. The point is that, in a pinch, you could get some extra
power out of a L297/L298-based solution, and it is a remarkably simple
circuit.

Hi Vlad,
I thought that using big power FET's was a super simple solution to
the higher power problem ?
