Note 1:
Stresses beyond those listed under Absolute Maximum Ratings temperature (TJ in °C) is calculated from the ambient temperature (TA in may cause permanent damage to the device. Exposure to any Absolute °C) and power dissipation (PD in Watts) according to the formula: Maximum Rating condition for extended periods may affect device TJ

C/W) is the package thermal impedance.
Note 2:
The LT8698SE and LT8698SE-1 are guaranteed to meet
Note 3:
This IC includes overtemperature protection that is intended to performance specifications from 0
˚
C to 125°C junction temperature. protect the device during overload conditions. Junction temperature will Specifications over the −40°C to 125°C operating junction temperature exceed 150°C when overtemperature protection is active. Continuous range are assured by design, characterization and correlation with operation above the specified maximum operating junction temperature statistical process controls. The LT8698SJ and LT8698SJ-1 are will reduce lifetime. guaranteed over the full −40°C to 150°C operating temperature range. High junction temperatures degrade operating lifetime. Operating lifetime
Note 4:
DUT configured in closed loop test circuit similar to page 36 CDP is de-rated at junction temperatures greater than 125°C. The junction charger application circuit.
Note 5:
Parameter not tested in production.
Note 6:
θ values are determined by simulation per JESD51 conditions, except θJA value is determined by simulation with demo board.
