1 / 11 page  Preliminary Datasheet LP28007 LP28007 – 02 May.-2013 Email: marketing@lowpowersemi.com www.lowpowersemi.com Page 1 of 11 Single and Dual Cell Li+ Battery Charger IC –LP28007 General Description The LP28007 is a fully integrated low cost single-cell Li-Ion battery charger IC ideal for portable applications. The LP28007 is capable of being powered up from AC adapter. The LP28007 enters sleep mode when AC adapter is removed. The LP28007 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. The LP28007 features 18V maximum rating voltages for AC adapter. The other features is under voltage protection.
