The Exposed Pad (EP) on the QFN−32 package bottom is thermally connected to the
die for improved heat transfer out of package. The exposed pad must be attached to a
heat−sinking conduit. The pad is electrically connected to the die, and must be electric-
ally and thermally connected to GND on the PC board.
