LTC4160/LTC4160-1
ELECTRICAL CHARACTERISTICS
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 LTC4160E/LTC4160E-1 are guaranteed to meet performance
specifications from 0°C to 85°C. Specifications over the –40°C to 85°C
operating temperature range are assured by design, characterization and
correlation with statistical process controls.
Note 3: The LTC4160E/LTC4160E-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.
Note 4: Total input current is the sum of quiescent current, IVBUSQ, and
measured current given by VCLPROG/RCLPROG • (hCLPROG + 1).
Note 5: The current limit features of this part are intended to protect the
IC from short term or intermittent fault conditions. Continuous operation
above the maximum specified pin current rating may result in device
degradation or failure.
Note 6: The bidirectional switcher’s supply current is bootstrapped to
VBUS and in the application will reflect back to VOUT by (VBUS/VOUT) •
1/efficiency. Total quiescent current is the sum of the current into the VOUT
pin plus the reflected current.
Note 7: hC/10 is expressed as a fraction of the measured full charge current
with indicated PROG resistor.
TYPICAL PERFORMANCE CHARACTERISTICS TA = 25°C, unless otherwise noted.
