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.
Note 2: All currents into pins are positive.
Note 3: Limits on the maximum rating is defined as whichever limit occurs
first. An internal clamp limits the GATE pin to a maximum of 12V above
source. Driving this pin to voltages beyond the clamp may damage the
device.
