Simple stepper motor question

Hi All,
Given all the discussion lately about Servo systems and such,
I hope this isn't too simple a question but I've been wanting to
build some kind of a small simple XY platform lately and have been
looking into stepper motors. I guess I've been using the term alot
around the family because my daughter gave me one for my birthday.
As luck would have it, I she picked a Minebea Astrosyn 23LQ-
C202-01H from Jameco which is a bipolar 1.9V .75A motor. I have
a wiring diagram and an example schematic of a driving circut
using discreet transistors but I've been trying to find a H-bridge
like chip which I could use instead. I want to drive the motor by
controling the phases in software so I don't want a translator
chip. So far about the only chip I've found which I "think" will
work is an L293B but I'm concerned about the low motor voltage.
From looking at the data sheets it seems that chips like the
TI 754410 and the L298 won't work with a motor voltage of only
1.9 volts. Is this the case with the L293B also?
Any one have any suggestions on a h-bridge which will work well
with the Minebea motor?
I've found some 5V 1A Vexta unipolar motors which I will probably
use when I actually build the platform so hopefully I won't have
this same problem.
Thanks,
Drew
