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 device pins are positive; all currents out of

device pins are negative. All voltages are referenced to GND unless

otherwise specified.

Note 3: An internal clamp limits VGATE to a minimum of 10V above VOUT.

Driving this pin voltages beyond this clamp may damage the device.

Note 4: These specifications are guaranteed by design.
