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:
5. θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief
TB379 for details.
6. For θJC, the “case temp” location is taken at the package top center.
Electrical Specifications VCC = 12V, VRS+ = 0V to 28V, VSENSE = 0V, RLOAD = 1MΩ, TA = +25°C unless otherwise specified.
Boldface limits apply over the operating temperature range, -40°C to +125°C.
Temperature data established by characterization.
