Exposed Die Attach Paddle.
For adequate thermal management, the exposed die paddle
should be soldered to a printed circuit board pad that is connected
to an electrically-isolated low-impedance inner layer and/or back-
side thermal plane(s) using multiple thermal vias. Do not connect
this pad to ground.
