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 LTC4088E is guaranteed to meet performance specifi cations
from 0°C to 85°C. Specifi cations over the – 40°C to 85°C operating
temperature range are assured by design, characterization and correlation
with statistical process controls.

Note 3: The LTC4088E includes overtemperature protection that is
intended to protect the device during momentary overload conditions.
Junction temperature will exceed 125°C when overtemperature protection
is active. Continuous operation above the specifi ed maximum operating
junction temperature may impair device reliability.
Note 4: Total input current is the sum of quiescent current, I
