So for the StepDC I chose the Ti DRV8801 H-bridge chip. It can handle up to 36V at up to 2.8A and it has built in overcurrent protection and monitoring. I chose this chip because it has a wide voltage range and supports a decent amount of current. While the driver can handle up to 36V I designed the circuit to be safe for 24V since components ruggedized for 36V would increase the cost a bit. 

Anyways here is the reference schematic from the datasheet:

I'll be using these components:

Next off is doing some component footprint creation and laying out the schematic!!
