6.2 Pin description
[1]
HVQFN and DHVQFN package die supply ground is connected to both the V
SS
pin and the exposed center
pad. The 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 PCB in the thermal pad region.
