Pinning information
6.1 Pinning
6.2 Pin description
[1]
DHVQFN package die supply ground is connected to both GND pin and exposed center pad. GND 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
printed-circuit board in the thermal pad region.
