† Notice: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

This is a stress rating only and functional operation of the device at those or any other conditions above those indicated

in the operational sections of this specification is not intended. Exposure to maximum rating conditions for extended

periods may affect device reliability.

‡ Notice: The device is not guaranteed to function outside its operating ratings.

Note 1: Device is ESD sensitive. Handling precautions are recommended. Human body model, 1.5 kΩ in series with

100 pF.

2: PD(MAX) = (TJ(MAX) – TA)/θJA, where θJA depends upon the printed circuit layout. A 5 square inch 4 layer,

0.62”, FR-4 PCB with 2 oz. finish copper weight per layer is used for the θJA.

ELECTRICAL CHARACTERISTICS

PVIN = VIN = VEN = 12V, VBST – VSW = 5V; TA = +25°C, unless otherwise noted. Bold values valid for –40°C ≤ TJ ≤
