The ISL6292 is an integrated single-cell Li-ion or Li-polymer battery charger capable of operating with an input voltage as low as 2. 4V. This charger is designed to work with various types of AC adapters or a USB port. The ISL6292 operates as a linear charger when the AC adapter is a voltage source. The battery is charged in a CC/CV (constant current/constant voltage) profile. The charge current is programmable with an external resistor up to 2A. The ISL6292 can also work with a current-limited adapter to minimize the thermal dissipation, in which case, the ISL6292 combines the benefits of both a linear charger and a pulse charger. The ISL6292 features charge current thermal foldback to guarantee safe operation when the printed circuit board is space limited for thermal dissipation. Additional features include preconditioning of an over-discharged battery, an NTC thermistor interface for charging the battery in a safe temperature range, automatic recharge, and thermally enhanced QFN or DFN packages.
