Linear Single Cell Li-Ion Battery Charger IC
General Description
The RT9513 is a fully integrated low cost single-cell LiIon battery charger IC ideal for portable applications. The RT9513 is capable of being powered up from AC adapter. The RT9513 enters sleep mode when AC adapter is removed.
The RT9513 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...
