DATASHEET ISL6292 FN9105 Rev.9.00 Li-ion/Li Polymer Battery Charger December 17, 2007 The ISL6292 is an integrated single-cell Li-ion or Li-polymer Features battery charger capable of operating with an input voltage as Complete Charger for Single-Cell Li-ion Batteries low as 2.4V. This charger is designed to work with various types of AC adapters or a USB port. Very Low Thermal Dissipation The ISL6292 operates as a linear charger when the AC Integrated Pass Element and Current Sensor adapter is a voltage source. The battery is charged in a No External Blocking Diode Required CC/CV (constant current/constant voltage) profile. The 1% Voltage Accuracy charge current is programmable with an external resistor up to 2A. The ISL6292 can also work with a current-limited Programmable Current Limit up to 2A adapter to minimize the thermal dissipation, in which case, Programmable End-of-Charge Current the ISL6292 combines the benefits of both a linear charger and a pulse charger. Charge Current Thermal Foldback The ISL6292 features charge current thermal foldback to NTC Thermistor Interface for Battery Temperature Monitor guarantee safe operation when the printed circuit board is Accepts Multiple Types of Adapters or USB BUS Power space limited for thermal dissipation. Additional features Guaranteed to Operate at 2.65V After Start-Up include preconditioning of an over-discharged battery, an NTC thermistor interface for charging the battery in a safe Ambient Temperature Range: -20C to +70C temperature range, automatic recharge, and thermally Thermally-Enhanced QFN Packages enhanced QFN or DFN packages.
