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 3: See Thermal Considerations.

The q denotes specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. VCC = 5V, unless otherwise noted.
ELECTRICAL CHARACTERISTICS
Note 4: Supply current includes PROG pin current (approximately 100
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: ITERM is expressed as a fraction of measured full charge current
with indicated PROG resistor.
