S-8261 Series BATTERY PROTECTION IC FOR 1-CELL PACK Rev.5.3_00 www.sii-ic.com © Seiko Instruments Inc., 2001-2012 The S-8261 Series is a lithium-ion / lithium polymer rechargeable battery protection IC incorporating high-accuracy voltage detection circuit and delay circuits. The S-8261 Series is 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 • Overcharge hysteresis voltage 3.9 V to 4.5 V (applicable in 5 mV step) 0.1 V to 0.4 V*1 Accuracy: ±25 mV (+25°C) and Accuracy: ±25 mV ±30 mV (−5°C to +55°C) The overcharge hysteresis voltage can be selected from the range 0.1 V to 0.4 V in 50 mV step. • Overdischarge detection voltage 2.0 V to 3.0 V (applicable in 10 mV step) Accuracy: ±50 mV • Overdischarge hysteresis voltage 0.0 V to 0.7 V*2 Accuracy: ±50 mV The overdischarge hysteresis voltage can be selected from the range 0.0 V to 0.7 V in 100 mV step. 0.05 V to 0.3 V (applicable in 10 mV step) Accuracy: ±15 mV 0.5 V (fixed) Accuracy: ±100 mV • Overcurrent 1 detection voltage • Overcurrent 2 detection voltage (2) High voltage device is used for charger connection pins (VM and CO pins: absolute maximum rating = 28 V). (3) Delay times (overcharge: tCU, overdischarge: tDL, overcurrent 1: tlOV1, overcurrent 2: tlOV2) are generated by an internal circuit. No external capacitor is necessary. Accuracy: ±20% (4) Three-step overcurrent detection circuit is included (overcurrent 1, overcurrent 2 and load short-circuiting). (5) 0 V battery charge function “Available” / “Unavailable” is selectable. (6) Power-down function “Yes” / “No” is selectable. (7) Charger detection function and abnormal charge current detection function • The overdischarge hysteresis is released by detecting negative voltage at the VM pin (−0.7 V typ.) (Charger detection function). • When the output voltage of the DO pin is high and the voltage at the VM pin is equal to or lower than the charger detection voltage (−0.7 V typ.), the output voltage of the CO pin goes low (Abnormal charge current detection function). (8) Low current consumption • Operation mode • Power-down mode 3.5 μA typ., 7.0 μA max. 0.1 μA max. (9) Wide operating temperature range −40°C to +85°C (10) Lead-free, Sn 100%, halogen-free*3 *1. Overcharge release voltage = Overcharge detection voltage − Overcharge hysteresis voltage (where overcharge release voltage < 3.8 V is prohibited.) *2. Overdischarge release voltage = Overdischarge detection voltage + Overdischarge hysteresis voltage (where overdischarge release voltage > 3.4 V is prohibited.) *3. Refer to “ Product Name Structure” for details. Applications • Lithium-ion rechargeable battery packs • Lithium polymer rechargeable battery packs Package • SOT-23-6 Seiko Instruments Inc. 1
