Both the SO-EP and TDFN-EP packages have an
exposed pad on the bottom of their package. These
pads are internally connected to GND. For the best
thermal conductivity, solder the exposed pad to the
4A, 20ns, Dual MOSFET Drivers

ground plane to dissipate 1.5W and 1.9W in SO-EP and
TDFN-EP packages, respectively. Do not use the
ground-connected pads as the only electrical ground
connection or ground return. Use GND (pin 3) as the
primary electrical ground connection.
