5.2 Pin description
[1]
HVQFN16 package die supply ground is connected to both VSS pin and exposed center pad. 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.
