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) Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(1) For more information on the PWP package, refer to TI technical brief, literature number SLMA002.

(2) Test board conditions:

1. 3” x 3”, 4 layers, thickness: 0.062”

2. 1.5 oz. copper traces located on the top of the PCB

3. 1.5 oz. copper ground plane on the bottom of the PCB

4. 0.5 oz. copper ground planes on the 2 internal layers

5. 12 thermal vias (see “Recommended Land Pattern” in applications section of this data sheet)

(3) Maximum power dissipation may be limited by over current protection.
