Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: The LTC4075E/LTC4075XE are guaranteed to meet the
performance speci?cations from 0°C to 70°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.
Note 4: Supply current includes IDC and ITERM pin current (approximately
100μA each) but does not include any current delivered to the battery
through the BAT pin.
Note 5: Supply current includes IUSB and ITERM pin current
(approximately 100μA each) but does not include any current delivered to
the battery through the BAT pin.
Note 6: This parameter is not applicable to the LTC4075X.
Note 7: Guaranteed by long term current density limitations.
See Thermal Considerations.
