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:
1. 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.
2. For θ_JC, the “case temp” location is the center of the exposed metal pad on the package underside.
Electrical Specifications Typical Values Are Tested at USB = CRDL = 5V and ambient temperature is at 25°C, Unless Otherwise Noted.
All Maximum and Minimum Values Are Guaranteed Under the Recommended Operating Conditions.
