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:

1.

θJA 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.

2.

θJC, “case temperature” location is at the center of the exposed metal pad on the package underside. See Tech Brief TB379.

Operating Specifications All Specifications Apply to Both the ISL9216 and ISL9217 Separately Over the Recommended Operating

Conditions, Unless Otherwise Specified.
