LTC4062

4062f

Note 1: Absolute Maximum Ratings are those values beyond which the life

of the device may be impaired.

Note 2: The LTC4062 is 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 correctly solder the exposed pad of the package to the

PC board will result in a thermal resistance much higher than 40°C/W.

(approximately 100µA each) but does not include any current delivered to

the battery through the BAT pin (approximately 100mA).

Note 5: This IC includes overtemperature protection that is intended to

protect the device during momentary overload conditions.

Overtemperature protection will become active at a junction temperature

greater than the maximum operating temperature. Continuous operation

above the specified maximum operating junction temperature may impair

device reliability.
