Thanks Irving, just for reference then the sinking arrangement I posted is correct?

Your first picture, yes... I'd try that first before making an intermediate driver.. or change the BOB for one with better output drivers...
.
And don't connect motor supply and BOB supply grounds else you'll lose the isolation.

K, so can I just leave the BOB xn (GND) unconnected, that had me confused mainly

[irving2008]

yes., assuming BOB xn(GND) and 5v GND are connected (I'd be surprised if they're not)
