Typical perForMance characTerisTics
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: Internal clamps limit the GATE and CPO pins to a minimum of 10V
above, and a diode below the corresponding V
IN
pin. Driving these pins to
voltages beyond the clamp may damage the device.
