The S-8204A Series includes a voltage detection circuit with high accuracy and a delay circuit, 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 this IC either for 3-series or 4-series cell pack.
By cascade connection using this IC, it is also possible to protect 5-series or more cells(*1) rechargeable lithium-ion battery pack.
◾Settable by external capacitor; Overcharge detection delay time, Overdischarge detection delay time, Discharge overcurrent detection delay time 1, Discharge overcurrent detection delay time 2 (Short circuit detection voltage delay time is internally fixed.)
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.
