You mean a driver to drive the MOSFETs of your H-bridge? If so, then I need to know if you are using P or N-channel. If N-channel, there are so many mosfet gate drivers like IR2181, IR2184, IR21844. I prefer you use the last one because it has the possiblity of programming dead time (to prevent shoot-through) b/w the MOSFETs of one arm in your H-bridge.
If using a microcontroller, then optocoupling could be good. If your pcb is well designed however, to prevent EMI, u can connect directly to the gate driver input.
