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 LTC4077E is guaranteed to meet the performance
speci?cations from 0°C to 85°C. Speci?cations 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 correctly solder the exposed backside of the package to
the PC board will result in a thermal resistance much higher than 40°C/W.
See Thermal Considerations.
Note 4: Supply current includes IDC pin current (approximately 100μA)
but does not include any current delivered to the battery through the BAT
pin.
Note 5: Supply current includes IUSB and IUSBL pin currents
(approximately 100μA each) but does not include any current delivered to
the battery through the BAT pin.
Note 6: Guaranteed by long term current density limitations.
Note 7: I C/10 is expressed as a fraction of measured full charge current.
Note 8: I C/2 is expressed as a fraction of measured full charge current.
Note 9: V CC is greater of DCIN or USBIN.
