Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 3:
Current limit guaranteed by design and/or correlation to static test. may cause permanent damage to the device. Exposure to any Absolute
Note 4:
This IC includes overtemperature protection that is intended Maximum Rating condition for extended periods may affect device to protect the device during momentary overload conditions. Junction reliability and lifetime. temperature will exceed 125°C when overtemperature protection is active.
Note 2:
The LT8582E is guaranteed to meet performance specifications Continuous operation over the specified maximum operating junction from 0°C to 125°C junction temperature. Specifications over the temperature may impair device reliability. –40°C to 125°C operating temperature range are assured by design,
