Features, Applications

The S-8261 series are lithium-ion/lithium polymer rechargeable battery protection ICs incorporating highaccuracy voltage detection circuit and delay circuit. The S-8261 series are suitable for protection of singlecell lithium ion/lithium polymer battery packs from overcharge, overdischarge and overcurrent.

Features

(1) Internal high accuracy voltage detection circuit Overcharge detection voltage 4.4 V (applicable 5 mV step) Accuracy: mV (+25C) and +55C) *1 Accuracy: 25 mV Overcharge hysteresis voltage 0.4 V The overcharge hysteresis voltage can be selected from the range 50 mV step. *1. Overcharge release voltage= Overcharge detection voltage - Overcharge hysteresis voltage (where overcharge release voltage< V is prohibited.) Overdischarge detection voltage (10 mV step) Accuracy: mV *2 Overdischarge hysteresis voltage 0.7 V Accuracy: 50 mV The overdischarge hysteresis voltage can be selected from the range 100 mV step. *2. Overdischarge release voltage= Overdischarge detection voltage + Overdischarge hysteresis voltage (where overdischarge release V is prohibited.) Overcurrent 1 detection voltage (10 mV step) Accuracy: 15 mV Overcurrent 2 detection voltage 5 V (fixed) Accuracy: mV (2) High voltage device is used for charger connection pins (VM and CO pins: absolute maximum rating 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) Either charge function or charge inhibition function for 0 V battery can be selected. (6) 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) (7) Low current consumption Operation 3.5 A typ. 7.0 A max. Power-down 0.1 A max. (8) Wide operating temperature range: +85C (9) Small package SOT-23-6, 6-Pin SNB(B)
