Battery Protection IC for 3-Serial or 4-Serial-Cell Pack S-8204A Series

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 representatives.

(*1). Overcharge hysteresis voltage n (n = 1 to 4) is selectable in 0 V, or in 0.1 V to 0.4 V in 50 mV step.
(Overcharge hysteresis voltage = Overcharge detection voltage – Overcharge release voltage) (*2). Overdischarge hysteresis voltage n (n = 1 to 4) is selectable in 0 V, or in 0.2 V to 0.7 V in 100 mV step.
(Overdischarge hysteresis voltage = Overdischarge release voltage – Overdischarge detection voltage)
