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: V CC is the greater of V IN , V OUT or V BAT .
Note 3: Pins 1, 3 and 8 (OUT) should be tied together with a low
impedance to ensure that the difference between the three pins does not
exceed 50mV. Pins 2, 4 and 5 (BAT) should be tied together with a low
impedance to ensure that the difference between the three pins does not
exceed 50mV.
Note 4: All voltage values are with respect to GND.
Note 5: This IC includes overtemperature protection that is intended
temperature will exceed 125°C when overtemperature protection is active.
Continuous operation above the speci?ed maximum operating junction
temperature may impair device reliability.
Note 6: The LTC4066/LTC4066-1 are guaranteed to meet performance
speci?cations from 0°C to 70°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 7: Guaranteed by long term current density limitations.
Note 8: Total input current is equal to this speci?cation plus 1.003 × I BAT
where I BAT is the charge current.
Note 9: Accuracy of programmed current may degrade for currents greater
than 1.5A.
