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/LTM8062AE are 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/LTM8062AI are 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
IN
Start is 3.3V above the
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.
