HWQFN package die supply ground is connected to both V
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.
