Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2: The LTC4054E-4.2 and the LTC4054XE-4.2 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 4: Supply current includes PROG pin current (approximately 100 μ A)
but does not include any current delivered to the battery through the BAT
pin (approximately 100mA).
Note 5: This parameter is not applicable to the LTC4054X.
Note 6: I TERM is expressed as a fraction of measured full charge current
with indicated PROG resistor.
Note 3: See Thermal Considerations.
