5 / 32 page  LTC4160/LTC4160-1 5 41601f TYPICAL PERFORMANCE CHARACTERISTICS USB Limited Load Current vs Battery Voltage (Battery Charger Disabled) USB Limited Load Current vs Battery Voltage (Battery Charger Disabled) Battery and VBUS Currents vs Load Current USB Limited Battery Charge Current vs Battery Voltage USB Limited Battery Charge Current vs Battery Voltage Battery and VBUS Currents vs Load Current 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. ELECTRICAL CHARACTERISTICS TA = 25°C, unless otherwise noted. 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.
