CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product

reliability and result in failures not covered by warranty.

NOTES:

4. JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See Tech

Brief TB379.

5. For JC, the “case temp” location is the center of the exposed metal pad on the package underside.

6. Thermal impedance depends on layout.

7. Includes margin limits.

Electrical Specifications VDDP = VDDS = 12V, TA = -40°C to +85°C unless otherwise noted. (Note 8) Typical values are at TA = +25°C.

Boldface limits apply over the operating temperature range, -40°C to +85°C.
