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.
+
150°C max junction temperature is intended for short periods of time to prevent shortening the lifetime. Operation close to +150°C junction may trigger the shutdown of
the device even before +150°C, since this number is specified as typical.
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 theta
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
