(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is intended to be functional, but do not ensure specific performance limits. For ensured specifications and conditions
see the Electrical Characteristics.
(2) If Military/Aerospace specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications.
(3) For detailed information on soldering plastic VSSOP packages refer to the Packaging Databook available from Texas Instruments.
(4) Current out of a pin is indicated as a negative number.
(5) The human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin.
Operating Ratings
VIN Supply Voltage +2.9V to 17V
PGD Off Voltage 0V to 17V
Junction Temp. Range −40°C to +85°C
Electrical Characteristics
Limits in standard type are for T
J
= 25°C only; limits in boldface type apply over the junction temperature (T
J
) range of -40°C
to +85°C. Minimum and Maximum limits are ensured through test, design, or statistical correlation. Typical values represent
the most likely parametric norm at T
J
= 25°C, and are provided for reference purposes only. Unless otherwise stated the
following conditions apply: VIN = 12V.
