Preliminary Datasheet
LP28007
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.
