HVQFN and DHVQFN package die supply ground is connected to both the V
pad. The V
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.
