Hi Amber,

Thanks for your post. 4-phase 5-wire stepper motors are generally knows as unipolar stepper motors. Please check out this application note, https://www.ti.com/lit/an/sloa312/sloa312.pdf. 

We also have this device https://www.ti.com/lit/ds/symlink/drv8805.pdf in our portfolio for unipolar stepper driving with STEP/DIR input indexer integrated.
