on Features The RT9503A is a fully integrated low cost single-cell LiIon battery charger IC ideal for portable applications. The RT9503A is capable of being powered up via theAC adapter and USB (Universal Serial Bus) port inputs. The RT9503A can automatically detect and select the AC adapter and the USB port as the power source for the charger. The RT9503A enters sleep mode when both supplies are removed. The RT9503A 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 prese
