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: Current into a pin is positive and current out of a pin is negative.
All Voltages referenced to GND
Note 3: The LTC4067 is guaranteed to meet performance speci?cations
from 0°C to 85°C. Speci?cations over the –40°C to 85°C ambient
operating temperature range are assured by design, characterization and
correlation with statistical process controls.
Note 5: This IC includes over-temperature protection that is intended
to protect the device during momentary overload conditions. Junction
temperature exceeds 125°C when over-temperature protection is active.
Continuous operation above the speci?ed maximum operating junction
temperature may result in device degradation or failure.
Note 6: V CC is the greater of V IN , V OUT or V BAT .
Note 7: Accuracy of programmed current may degrade for currents greater
than 1A.
Note 8: CLPROG soft-start scales with inverse of CLPROG resistor. If
R CLPROG = 2k, then I SS = 0.6mA/μs.
Note 4: Speci?cation is guaranteed by design and not 100% tested in
production.
