BATTERY PROTECTION IC FOR A SINGLE 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 single-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 V to 4.4 V (5 mV-step) Accuracy of ± 25 mV(+25°C) and ± 30 mV(-5°C to +55°C) *1 · Overcharge release voltage 3.8 V to 4.4 V Accuracy of ±50 mV
*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 50mV steps. (However, selection "Overcharge release voltage<3.8 V" is enabled.)
· Overdischarge detection voltage: · Overdischarge release voltage:
2.0 V to 3.0 V (100 mV-step) Accuracy of ±80 mV *2 2.0 V to 3.4 V Accuracy of ±100 mV
*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 100mV steps. (However, selection "Overdischarge release voltage>3.4 V" is enabled.)
· Overcurrent 1 detection voltage: 0.05 V to 0.3 V (5 mV-step) Accuracy of ±20 mV · Overcurrent 2 detection voltage: 0. 5 V (fixed) Accuracy of ±100 mV (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, 5-Pin SON(A)
Applications
· Lithium-ion rechargeable battery packs · Lithium- polymer rechargeable battery packs
Packages
· SOT-23-5 (PKG drawing code : MP005-A) · 5-Pin SON(A) (PKG drawing code : PN005-A)
