ELECTRICAL CHARACTERISTICS
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 LTM8061E is guaranteed to meet performance specifications
from 0°C to 125°C. Specifications over the –40°C to 125°C internal
temperature range are assured by design, characterization and correlation
with statistical process controls. LTM8061I 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:
The maximum BAT charge current is reduced by thermal foldback.
See the Typical Performance Characteristics section for details.
