| Abstract: | A charger controller IC (integrated circuit) which could provide different charging modes such as constant current charge,constant voltage charge,over-voltage charge and floating charge was proposed.Cooperated with an MCU,the IC could make the different rechargeable batteries improve their charging efficiency and reliability according to different applications.The design of the system and main modules were discussed in detail.The chip was designed and fabri- cated in 1.5μm 50 V BCD technology.Test results showed that the chip works normally.And all expected functions of modules as well as that of system were successfully achieved. |
