stepper motor driver circuit

I need to design a drive circuit for a pm2515-03 stepper motor, rated at 5V and 0.5A (Unipolar). I am looking for advice on the best switching device to use for this project.

I don't understand the term "best switching device". Do you need to have finer controll on the angle that the steppers rating?

You may either use Mosfets or transistors or dedicated stepper driver Ic's. All are "best switching devices" but depends on your design and requiremnets. Good luck.

I meant between MOSFETs, BJTs, Darlingtons, IGBTs....... Which would be the best to use and why?

Because unipolar pm2515-03 is restricted to medium speeds by design, any small power transistor (BJT, darlington or FET) can do, also integrated drivers.
 

I suggest you to use FET bcos voltage and current rating is low so u dnt need other device.U can also use BJT,But i think FET is perfect for it
