Preliminary Datasheet LP28006 Single and Dual Cell Li+ Battery Charger IC –LP28006 General Description The LP28006 is a fully integrated low cost single-cell Li-Ion battery charger IC ideal for portable applications. The LP28006 is capable of being powered up from AC adapter. The LP28006 enters sleep mode when AC adapter is removed. The LP28006 optimizes the charging task by using a control algorithm including preconditioning mode, fast charge mode and constant voltage mode. The charging task is terminated as the charge current drops below the preset threshold. The AC adapter charge current can be programmed up to 1A with an external resister. The internal thermal feedback circuitry regulates the die temperature to optimize the charge rate for all ambient temperatures.
