ELECTRICAL 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.

The

l denotes the speciﬁcations which apply over the full operating

temperature range, otherwise speciﬁcations are at TA = 25°C. VOUT = VDD, VDD = 9V to 26.5V, unless otherwise noted.

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 minimum of 6V above

IN. Driving this pin to voltages beyond this clamp may damage the device.
