Note 1: Stresses beyond those listed under Absolute
Maximum Ratings may cause permanent damage to the
device. Exposure to any Absolute Maximum Rating
condition for extended periods may affect device
reliability and lifetime.
Note 5: The 2.6V maximum buck undervoltage lockout
(VUVLO_BUCK) exit threshold must first be exceeded
before the minimum VBAT specification applies.
Note 6: IC/10 is expressed as a fraction of measured full
charge current with indicated PROG resistor.
Note 2: The EUP8080 is guaranteed to meet
performance specifications form 0℃to 85℃.
Specifications over the -40℃ to 85℃ 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 ground plane will result in a
thermal resistance much higher than 43℃/W.
Note 4: Although the EUP8080 charger functions
properly at 3.75V, full charge current requires an input
voltage greater then the desired final battery voltage per
△VUVCL1 specification.
