Note 1:
Stresses beyond those listed under Absolute Maximum Ratings LT8330I is guaranteed over the full –40°C to 125°C operating junction may cause permanent damage to the device. Exposure to any Absolute temperature range. The LT8330H is guaranteed over the full –40°C to Maximum Rating condition for extended periods may affect device 150°C operating junction temperature range. High junction temperatures reliability and lifetime. degrade operating lifetimes. Operating lifetime is derated at junction
Note 2:
INTV temperatures greater than 125°C. CC cannot be externally driven. No additional components or loading is allowed on this pin.
Note 4:
The IC includes overtemperature protection that is intended to
Note 3:
The LT8330E 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. Rev.
