LTC4058-4.2/LTC4058X-4.2
sn405842 405842fs
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.

ELECTRICAL CHARACTERISTICS
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:
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.
Note 7:
I
TERM
is expressed as a fraction of measured full charge current
with indicated PROG resistor.
