SM72441: Use with only 2 MOSFETs

Part Number:SM72441

Hi,

Can I use it with just the 2 synchronous boost MOSFETs? There is no need in my application to buck the PV voltage (i.e. batt volts is always > PV volts)

Second, I have an unusual requirement in that I need to be able to discharge the batteries into the PV panels. (batt volts will still be < PV volts, so the same 2 MOSFETs will work. The boost converter will act like a buck converter, when the current is reversed).  So I need current to reverse from the battery into the PV with a current limit. Can you think of a way to "cheat" the signals to it, (I have a big microcontroller in the system) to coax the IC to do that?

TIA
