in this pic it show block diagram of st powerstep it use 8 mosfet and buffer to drive them . so i can use 8 mosfet to avoid any miss clocking  and i should use...

It will be cost effective as well Can I put resistor to limite current? Or I can use another mosfet with opamp to adjust current right?
