The S-8225B Series includes high-accuracy voltage detection circuits and delay circuits, and can monitor the status of

3-serial to 5-serial cell lithium-ion rechargeable battery in single use. By switching the voltage level which is applied to the

SEL1 pin and SEL2 pin, users are able to use the S-8225B Series for 3-serial to 5-serial cell pack.

*1. Overcharge hysteresis voltage n (n = 1 to 5) 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 5) 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)
