Note 2: All currents into pins are positive, all voltages are referenced to
GND unless otherwise specified.
Note 3: An internal clamp limits the GATE pin to a minimum of 10V above
Note 3: An internal clamp limits the GATE pin to a minimum of 10V above
IN or 100V above GND. Driving this pin to voltages beyond this clamp may
damage the device.
