BATTERY PROTECTION IC  
FOR 1-CELL PACK  
S-8241 Series  
The S-8241 Series is a series of lithium ion/lithium polymer rechargeable battery  
protection ICs incorporating high-accuracy voltage detection circuits and delay  
circuits.  
These ICs are suitable for protection of 1-cell lithium ion/lithium polymer battery  
packs from overcharge, overdischarge and overcurrent.  
„ Features  
(1) Internal high-accuracy voltage detection circuit  
Overcharge detection voltage: 3.9 to 4.4 V (5 mV-step)  
Accuracy of ±25 mV(+25 °C) and ± 30 mV(5 to +55 °C)  
3.8 to 4.4 V *1 Accuracy of ±50 mV  
Overdischarge detection voltage: 2.0 to 3.0 V (100 mV-step) Accuracy of ±80 mV  
Overdischarge release voltage: Accuracy of ±100 mV  
2.0 to 3.4 V *2  
Overcurrent 1 detection voltage: 0.05 to 0.3 V (5 mV-step) Accuracy of ±20 mV  
Accuracy of ±100 mV  
Overcharge release voltage:  
Overcurrent 2 detection voltage: 0.5 V (fixed)  
(2) A high voltage withstand device is used for charger connection pins  
(VM and CO pins: Absolute maximum rating = 26 V)  
(3) Delay times (overcharge: tCU; overdischarge: tDL; overcurrent 1: tlOV1; overcurrent 2: tlOV2) are generated  
by an internal circuit. (External capacitors are unnecessary.) Accuracy of ±30%  
(4) Internal three-step overcurrent detection circuit (overcurrent 1, overcurrent 2, and load short-circuiting)  
(5) Either the 0 V battery charging function or 0 V battery charge inhibiting function can be selected.  
(6) Products with and without a power-down function can be selected.  
(7) Charger detection function and abnormal charge current detection function  
The overdischarge hysterisis is released by detecting a negative VM pin voltage (typ. 1.3 V) (Charger detection  
function).  
If the output voltage at DO pin is high and the VM pin voltage becomes equal to or lower than the charger detection  
voltage (typ. 1.3 V), the output voltage at CO pin goes low (Abnormal charge current detection function).  
(8) Low current consumption  
Operation:  
3.0 μA typ. 5.0 μA max.  
Power-down mode: 0.1 μA max.  
(9) Wide operating temperature range: 40 to +85 °C  
(10) Small package SOT-23-5, SNT-6A  
(11) Lead-free products  
*1. Overcharge release voltage = Overcharge detection voltage - Overcharge hysteresis  
The overcharge hysteresis can be selected in the range 0.0, or 0.1 to 0.4 V in 50 mV steps. (However, selection  
“Overcharge release voltage<3.8 V” is enabled.)  
*2. Overdischarge release voltage = Overdischarge detection voltage + Overdischarge hysteresis  
The overdischarge hysteresis can be selected in the range 0.0 to 0.7 V in 100 mV steps. (However, selection  
“Overdischarge release voltage>3.4 V” is enabled.)
