RP1553
Linear Single Cell Li-Ion Battery Charger IC
General Description
The RP1553 is a fully integrated low cost single-cell Li-
Ion battery charger IC ideal for portable applications. The
RP1553 is capable of being powered up from AC adapter.
The RP1553 enters sleep mode when AC adapter is
removed.
The RP1553 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 RP1553 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.
