Electrical Characteristics (Continued)

Specifications with standard type are for T

J = 25˚C only; limits in boldface type apply over the full Operating Junction Tempera-

ture (T

J) range. Minimum and Maximum limits are guaranteed through test, design, or statistical correlation. Typical values rep-

resent the most likely parametric norm at T

J = 25˚C, and are provided for reference purposes only. Unless otherwise stated the

following conditions apply: V

IN = 24V, RON = 200k

Ω. (Note 3).

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 TA =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 VCC 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 discharge through a 1.5k

Ω resistor into each pin. The human body ESD compliance level for Pin 7 and 8 is

1000V.

Note 6: For devices procurred in the LLP-8 package the Rds(on) limits are guaranteed by design characterization data only.
