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.
