Overview
RT9515 Linear Single Cell Li-Ion Battery Charger IC General Description The RT9515 is a fully integrated low cost single-cell LiIon battery charger IC ideal for portable applications.
The RT9515 is capable of being powered up from AC adapter.
The RT9515 enters sleep mode when AC adapter is removed.
The RT9515 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 RT9515 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.
