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 LTC4065L is tested under pulsed load conditions such that
T
J
≈ T
A
. The LTC4065L is guaranteed to meet performance specifica-
tions from 0°C to 70°C. Specifications over the –40°C to 85°C operating
temperature range are assured by design, characterization and correlation
with statistical process controls.
Note 3: Failure to solder the exposed backside of the package to the PC
board ground plane will result in a thermal resistance much higher than
rated.

Note 4: Although the LTC4065L functions properly at 3.75V input, full
charge current requires an input voltage greater than the desired final bat-
tery voltage per the ΔV
UVCL1
specification.
Note 5: I
C/10
is expressed as a fraction of measured full charge current
with indicated PROG resistor.
Note 6: This IC 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 specified maximum operating junction
temperature may impair device reliability.
Note 7: This parameter is not applicable to the LTC4065LX.
