Hi.
Pin1 is the source for the low side mosfet (NPN)an one side of the H-bridge, Pin4 is the source for the low side mosfet(NPN) on the other side of the H-bridge.
Just connect them to ground. If you want to use a sense resistor you would connect it here.
The question that drives me hazy:

Am I, or the others crazy?
