(1)
Absolute maximum ratings indicate limits beyond which damage to the device may occur. Operating ratings indicate conditions for
which the device operates correctly. Operating Ratings do not imply specified performance limits.
(2)
If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and
specifications.
(3)
ESD using the human body model which is a 100pF capacitor discharged through a 1.5 k
Ω resistor into each pin.

The power MOSFETs can run on a separate 1V to 14V rail (Input voltage, VIN). Practical lower limit of VIN depends on selection of the
external MOSFET. See the MOSFET GATE DRIVERS section under Application Information for further details.
Electrical Characteristics
VCC = 3.3V unless otherwise indicated. Typicals and limits appearing in plain type apply for TA= TJ= 25°C. Limits appearing in
boldface type apply over full Operating Temperature Range. Datasheet min/max specification limits are specified by design,
test, or statistical analysis.
