You use H-bridges and half-bridge circuit to drive bipolar steppers because you need to run current through the coils in both directions.

Unipolar steppers only run current through the coils in one direction, so you use darligntons. ULN2803 is what I always go with for unipolar steppers. Eight darlingtons on one chip, half an amp on each one.
