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 2: The LTM8062E is guaranteed to meet performance specifications
from 0°C to 125°C internal. Specifications over the full –40°C to
125°C internal operating temperature range are assured by design,
characterization and correlation with statistical process controls. The
LTM8062I is guaranteed to meet specifications over the full –40°C to
125°C internal operating temperature range. Note that the maximum

internal temperature is determined by specific operating conditions in
conjunction with board layout, the rated package thermal resistance and
other environmental factors.
Note 3: This parameter is valid for programmed output battery float
voltages ≤ 4.2V. For other float voltages, V
programmed output battery float voltage. This parameter is guaranteed by
design, characterization, and correlation with statistical process controls.
Note 4: The maximum BAT charging current is reduced by thermal
foldback. See the Typical Performance Characteristics for details.
