EP Exposed Pad Thermal The Exposed Pad (EP) on the QFN−64 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 electrically and thermally connected to GND on the PC board.
