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
specifi ed.

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.
