RT9502 Linear Single Cell Li-Ion Battery Charger IC with Dual Input Supply General Description The RT9502 is a fully integrated low cost single-cell LiIon battery charger IC ideal for portable applications. The RT9502 is capable of being powered up from AC adapter and USB (Universal Serial Bus) port inputs. The RT9502 can automatically detect and select the AC adapter and the USB port as the power source for the charger. The RT9502 enters sleep mode when both supplies are removed. The RT9502 optimizes the charging task by using a control algorithm including precondition mode, fast charge mode and constant voltage mode. The charging task is terminated as the charge current drops below the preset threshold.
