CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
3. All voltages are with respect to GND.
4. 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.
5. For θ_JC, the “case temp” location is the center of the exposed metal pad on the package underside.
Electrical Specifications Recommended operating conditions unless otherwise noted. V_IN = 3.3V ±10% (ISL6410) or 5V ±10%
(ISL6410A), T_A = 25°C (Note 6).
