ISL6292 Data Sheet December 17, 2007 FN9105.9 Li-ion/Li Polymer Battery Charger Features The ISL6292 is an integrated single-cell Li-ion or Li-polymer Complete Charger for Single-Cell Li-ion Batteries battery charger capable of operating with an input voltage as Very Low Thermal Dissipation low as 2.4V. This charger is designed to work with various types of AC adapters or a USB port. Integrated Pass Element and Current Sensor The ISL6292 operates as a linear charger when the AC No External Blocking Diode Required adapter is a voltage source. The battery is charged in a 1% Voltage Accuracy CC/CV (constant current/constant voltage) profile. The Programmable Current Limit up to 2A charge current is programmable with an external resistor up to 2A. The ISL6292 can also work with a current-limited Programmable End-of-Charge Current adapter to minimize the thermal dissipation, in which case, Charge Current Thermal Foldback the ISL6292 combines the benefits of both a linear charger and a pulse charger. NTC Thermistor Interface for Battery Temperature Monitor Accepts Multiple Types of Adapters or USB BUS Power The ISL6292 features charge current thermal foldback to guarantee safe operation when the printed circuit board is Guaranteed to Operate at 2.65V After Start-Up space limited for thermal dissipation. Additional features Ambient Temperature Range: -20C to +70C include preconditioning of an over-discharged battery, an NTC thermistor interface for charging the battery in a safe Thermally-Enhanced QFN Packages temperature range, automatic recharge, and thermally Handheld Devices, including Medical Handhelds enhanced QFN or DFN packages.
