Since high and fast currents circulate in the circuit, it is mandatory to build a single ground point in
the system.
This pin provides the V GS to drive the Low side power MOSFET.
This pin is connected to the output of the half bridge and is referenced for the High side switch.
This pin provides the V GS to drive the High side power MOSFET.
The gate drive of the High side switch is derived from this voltage.
