Note 1:
Stresses beyond those listed under Absolute Maximum Ratings may
cause permanent damage to the device. Exposure to any Absolute Maximum
Rating condition for extended periods may affect device reliability and lifetime.
Note 2:
The LT8620E is guaranteed to meet performance specifications
from 0°C to 125°C junction temperature. Specifications over the –40°C
to 125°C operating junction temperature range are assured by design,
characterization, and correlation with statistical process controls. The
LT8620I is guaranteed over the full –40°C to 125°C operating junction
temperature range. The LT8620H is guaranteed over the full
−40°C
to
150°C operating junction temperature range. The LT8620MP is 100%
tested and guaranteed over the full
−55°C
to 150°C operating junction
temperature range. High junction temperatures degrade operating lifetimes.
Operating lifetime is derated at junction temperatures greater than 125°C.
Note 3:
This IC includes overtemperature protection that is intended to protect
the device during overload conditions. Junction temperature will exceed 150°C
when overtemperature protection is active. Continuous operation above the
specified maximum operating junction temperature will reduce lifetime.
