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. The
LP28006 features 18V maximum rating voltages for AC
adapter. The other features are under voltage protection,
over voltage protection for AC adapter supply and battery
temperature monitoring.
