RT9514 Linear Single Cell Li-Ion Battery Charger IC General Description The RT9514 is a fully integrated low cost single-cell LiIon battery charger IC ideal for portable applications. The RT9514 is capable of being powered up from AC adapter. The RT9514 enters sleep mode when AC adapter is removed. The RT9514 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.
