Default stepper motor driver help

hey

im currently using the UC3770A stepper motor driver chip which has known noise problems, i was told they dont even make that chip any more because of the problems it had.

CURRENT DRIVER:

Im wondering if anyone knows of a comparable driver, something that doesnt have problems... or if you just know of a good stepper motor driver still in production..

thanks very much

The UCN5804 is obsolete! Try two PBL3717A for one motor (bipolar)
