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 LTC4065/LTC4065A are guaranteed to meet performance
specifications 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
Note 4: Although the LTC4065 functions properly at 3.75V, full charge
current requires an input voltage greater than the desired final battery
voltage per the ? V 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.
