[1] DHVQFN20 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.
