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 LTC4098E/LTC4098E-1 are guaranteed to meet performance
speci?cations from 0°C to 85°C. Speci?cations over the – 40°C to 85°C
operating temperature range are assured by design, characterization and
correlation with statistical process controls.
Note 3: The LTC4098E/LTC4098E-1 include 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 impair device reliability or
permanently damage the device.
Note 4: Total input current, I VBUS(LIM) , is equal to I VBUSQ + (V CLPROG /
R CLPROG ) ? (h CLPROG + 1).
Note 5: h C/10 is expressed as a fraction of measured full charge current
with a 5k PROG resistor.
