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: An internal clamp limits VGATE to a minimum of 4.5V above VOUT.
Driving this pin to voltages beyond this clamp may damage the device.
