ELECTRICAL CHARACTERISTICS
Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2: The LTC4058E-4.2/LTC4058XE-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: Failure to 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 PROG pin current (approximately 100 A)
but does not include any current delivered to the battery through the BAT
pin (approximately 100mA).
Note 5: For all Li-Ion applications, the BSENSE pin must be electrically
connected to the BAT pin.
Note 6: This parameter is not applicable to the LTC4058X.
