LT8606/LT8606B
ELECTRICAL CHARACTERISTICS Note 1:
Stresses beyond those listed under Absolute Maximum Ratings temperature range. The LT8606H is guaranteed over the full –40°C to may cause permanent damage to the device. Exposure to any Absolute 150°C operating junction temperature range. High junction temperatures Maximum Rating condition for extended periods may affect device degrade operating lifetimes. Operating lifetime is derated at junction reliability and lifetime. Absolute Maximum Ratings are those values beyond temperatures greater than 125°C. which the life of a device may be impaired.
Note 3:
This IC includes overtemperature protection that is intended to
Note 2:
The LT8606E is guaranteed to meet performance specifications protect the device during overload conditions. Junction temperature will from 0°C to 125°C junction temperature. Specifications over the –40°C exceed 150°C when overtemperature protection is active. Continuous to 125°C operating junction temperature range are assured by design, operation above the specified maximum operating junction temperature characterization, and correlation with statistical process controls. The will reduce lifetime. LT8606I is guaranteed over the full –40°C to 125°C operating junction
