RT9502 datasheet,pdf资料(Linear Single Cell Li-Ion Battery Charger IC withDual Input Supply)

The RT9502 is a fully integrated low cost single-cell Li-

Ion 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
