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: Do not apply a positive or negative voltage source to these pins,

otherwise permanent damage may occur.

Note 3: The LT8357E is guaranteed to meet performance specifications

from 0°C to 125°C operating junction temperature. Specifications over

the -40°C to 125°C operating junction temperature range are assured by

design, characterization and correlation with statistical process controls.

ELECTRICAL CHARACTERISTICS The

denotes specifications which apply over the full operating junction

temperature range, otherwise specifications are at TA = 25°C (Note 3). VIN = 12V, EN/UVLO = 1.5V, CINTVCC = 2.2µF to GND, unless

otherwise noted.

The LT8357J and LT8357H are guaranteed over the −40°C to 150°C

operating junction temperature range. High junction temperatures degrade

operating lifetimes. Operating lifetime is derated at junction temperatures

greater than 125°C.

Note 4: The LT8357 includes over temperature protection that is intended

to protect the device during momentary overload conditions. Junction

temperature will exceed 150°C when over temperature protection is active.

Continuous operation above the specified absolute maximum operating

junction temperature may impair device reliability.
