Note 1: Stresses beyond those listed under Absolute Maximum Ratings

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

Maximum Rating 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: Internal clamps limit the GATE and CPO pins to a minimum of 5V

above, and a diode below SOURCE. Driving these pins to voltages beyond

the clamp may damage the device.
