These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(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 specifications and test conditions, see the Electrical Characteristics.
(2) The human body model is a 100pF capacitor discharged through a 1.5kΩ resistor into each pin.
(3) For detailed information on soldering plastic HTSSOP and WSON packages, refer to the Packaging Data Book.

(1) Typical specifications represent the most likely parametric norm at 25°C operation.
(2) All electrical characteristics having room temperature limits are tested during production with T
A
= 25°C. All hot and cold limits are
specified by correlating the electrical characteristics to process and temperature variations and applying statistical process control.
(3) V
CC
provides bias for the internal gate drive and control circuits. Device thermal limitations limit external loading.
