BQ24773: ACFET/RBFET MOSFETs

To separate ACFET and RBFET gate drive, how many gate drive pins do you need to connect to source and gate?

Dear Wang,

My question is, If We don't use common source 2 N-channel MOSFET, instead of that if we use 2 N-channel MOSFET IC having separate source and gate pins and then we short both gate pins and source pins together connecting to ACDRV and CMSRC respectively, What would be the effect on performance? Can we use this type of configuration?

Could you draw your circuit? And where is CMSRC connected to? Left or right? 

For your reference: Type-1 MOSFET (2- N channel MOSFETs, source(S1 & S2) and gate(G1 & G2) pins of each MOSFET are not shorted internally)

                               Type-2 MOSFET (2- N channel MOSFETs, source and gate pins of each MOSFET are  shorted internally)

As highlighted in red colour two MOSFETs used as ACFET(left side) & RBFET(right side), here what if we use Type-1 MOSFET instead of using Type-2? If we uses such type of MSOFET(Type-1) and manually connect both source(S1 & S2) together and then we connect it to CMSRC, the same way we do it for gate pins (G1 & G2) and connect it to ACDRV , would it affect to performance? 

Thanks Wang.
