HVQFN package die supply ground is connected to both V SS pin and exposed center pad. V SS pin must be
connected to supply ground for proper device operation. For enhanced thermal, electrical, and board level
performance, the exposed pad needs to be soldered to the board using a corresponding thermal pad on the
board and for proper heat conduction through the board, thermal vias need to be incorporated in the
printed-circuit board in the thermal pad region.
