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: Based on long-term current density limitations.

Note 3: The LTC3219 is guaranteed to meet performance specifications

from 0°C to 85°C. Specifications over the – 40°C to 85°C operating

temperature range are assured by design, characterization and correlation

with statistical process controls.

Note 4: This IC includes overtemperature protection that is intended

to protect the device during momentary overload conditions. Junction

temperature will exceed 125°C when overtemperature protection is active.

Continuous operation above the specified maximum operating junction

temperature may result in device degradation or failure.

Note 7: Guaranteed by design.
