Note 1:
Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the
device is intended to be functional. For guaranteed specifications and test conditions, see the Electrical Characteristics.
Note 2:
For detailed information on soldering plastic MSOP and LLP packages, refer to the Packaging Data Book available from National Semiconductor
Corporation.
Note 3:
All limits are guaranteed. All electrical characteristics having room temperature limits are tested during production with T
A = TJ = 25°C. All hot and cold
limits are guaranteed by correlating the electrical characteristics to process and temperature variations and applying statistical process control.
Note 4:
The V
CC output is intended as a self bias for the internal gate drive power and control circuits. Device thermal limitations limit external loading.
Note 5:
The human body model is a 100pF capacitor discharged through a 1.5k
resistor into each pin.
Note 6:
For devices procured in the LLP-8 package the Rds(on) limits are guaranteed by design characterization data only.
