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
OUT. Driving this pin to voltages beyond the clamp may damage the device.
Note 4: This IC includes overtemperature protection that is intended
to protect the device during momentary overload conditions. Junction
