BATTERY PROTECTION IC
FOR 3-SERIES OR 4-SERIES CELL PACK
The S-8204A Series includes high-accuracy voltage detection circuits and delay circuits, in single use, makes it
possible for users to monitor the status of 3-series or 4-series cell lithium-ion rechargeable battery. By switching
the voltage level which is applied to the SEL pin, users are able to use the S-8204A Series either for 3-series or
4-series cell pack.
By cascade connection using the S-8204A Series, it is also possible to protect 6-series or more cells*1
lithium-ion rechargeable battery pack.
*1. Refer to the application note for connection examples of protection circuit for 6-series or more cells.
In case of protecting 5-series cell lithium-ion rechargeable battery pack, contact our sales office.
