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. ACSET may be operated 1V below GND if the current through ACSET is limited to less than 1mA.
5. θ_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.
6. For θ_JC, the “case temp” location is the center of the exposed metal pad on the package underside.
