Note 2: All currents into the device pins are positive; all currents out of
device pins are negative. All voltages are referenced to ground unless
otherwise specifi ed.
Note 3: The GATE pin is internally limited to a minimum of 11.5V. Driving
this pin to voltages beyond the clamp may damage the part.
