The l denotes the specifications which apply over the full operating

temperature range, otherwise specifications are at TA = 25°C. VCC = 12V unless otherwise noted.

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: An internal clamp limits the GATE pin to a minimum of 10V above

the OUT pin. Driving this pin to voltages beyond the clamp may damage

the device.

Note 4: Resting voltage after turn-on.
