Note 1: Stresses beyond those listed under Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to any Absolute

Maximum Rating condition for extended periods may affect device

reliability and lifetime.

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

IN or 100V above GND. Driving this pin to voltages beyond this clamp may

damage the device.
