[1] HVQFN package die supply ground is connected to both the VSS pin and the exposed center pad. The VSS
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 PCB in the thermal pad region.
