I'd like to use half-bridges in the DRV8850 in parallel (OUT1 and OUT2 connected together), and connect the motor between this combined output and ground. I expect that I can drive the motor with more current that way. I only need to turn the motor in one direction. Each MOSFET in the bridge has got an individual logic control input.
I need to limit current during motor startup, or accidental stall. I'm reading 7.3.3 in the datasheet, and my question is about current sensing in DRV8850. Is the current out of the VPROPI proportional to the sum of current in the high side MOSFETs?
p.s. If the pin VPROPI outputs current proportional to current flowing in the bridge, shouldn't it be called IPROPI?
