5.1 Electrostatic Discharge Caution
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) All Voltages are with respect to the potential at the GND pin.
(2) Absolute Maximum Ratings are limits beyond which damage can occur. Operating Ratings are conditions under which operation of the
device is guaranteed. Operating Ratings do not imply guaranteed performance limits. For guaranteed performance limits and associated
test conditions, see the Electrical Characteristics tables.
(3) If Military/Aerospace specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications.
(4) For further information on these packages please refer to the following Application Notes; AN1112 DSBGA Package Wafer Level Chip
Scale Package, AN1187 Leadless Leadframe Package.
(5) Internal thermal shutdown circuitry protects the device from permanent damage.
(6) The human body model is 100pF discharged through a 1.5kΩ resistor into each pin. The machine model is a 200pF capacitor
discharged directly into each pin.

(1) Absolute Maximum Ratings are limits beyond which damage can occur. Operating Ratings are conditions under which operation of the
device is guaranteed. Operating Ratings do not imply guaranteed performance limits. For guaranteed performance limits and associated
test conditions, see the Electrical Characteristics tables.
(2) The maximum ambient temperature (T
A(max)
) is dependant on the maximum operating junction temperature (T
J(max-op)
= 125°C), the
maximum power dissipation of the device in the application (P
D(max)
), and the junction to ambient thermal resistance of the part/package
in the application (θ
JA
), as given by the following equation: T
A(max)
= T
J(max-op)
- (θ
JA
× P
