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 maximum of 6.5V above

the SOURCE pin. Driving either GATE or SOURCE pin to voltages beyond

the clamp may damage the device.
