PVCC (Pin 16)
Power supply pin for the MOSFET drives. Connect this pin to
a 5V supply and locally decouple using a quality 1µF
ceramic capacitor.
GND and PGND (Pins 25 and 14)
Connect these pins to the circuit ground using the shortest
possible paths. All internal small-signal circuitry is
referenced to the GND pin. LGATE drive is referenced to the
PGND pin.
