5.2 Pin description

[1] HVQFN24 package die supply ground is connected to both V

pin and exposed center pad. V

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.
