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
Note 3: IN1 and IN2 should be tied together with a low impedance to
ensure that the difference between the two pins does not exceed 100mV.
Note 4: All voltage values are with respect to GND.
Note 5: This IC includes 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 specifi ed maximum operating junction
temperature may impair device reliability.

Note 6: The LTC4055EUF/LTC4055EUF-1 are guaranteed to meet
performance specifi cations from 0°C to 85°C. Specifi 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: Accuracy of programmed current may degrade for currents greater
than 1A.
