LTC4069-4.4

406944fa
The
l denotes specications which apply over the full operating temperature range, otherwise specications are TA = 25°C.
VCC = 5V, VBAT = 3.8V, VNTC = 0V unless otherwise specied. (Note 2)
ELECTRICAL CHARACTERISTICS
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 LTC4069-4.4 is guaranteed to meet performance
specications from 0°C to 85°C. Specications 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 LTC4069-4.4 functions properly at 3.75V, full charge
current requires an input voltage greater than the desired nal battery
voltage per the ΔVUVCL1 specication.
Note 5: IC/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 specied maximum operating junction
temperature may impair device reliability.
