Note 3. An internal clamp limits the OUT pin to a minimum of 100V above
V
SS
. Driving this pin with more current than 1mA may damage the device.
Note 4. An internal clamp limits the GATE pin to a minimum of 10V above
IN or 100V above V
SS
. Driving this pin to voltages beyond the clamp may
damage the device.
