Rev.5.4_03

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

3.900 V to 4.500 V (applicable in 5 mV step) Accuracy: 25 mV (25C) and

30 mV (5C to 55C)

 Overcharge hysteresis voltage

0.1 V to 0.4 V^*1

Accuracy: 25 mV

The overcharge hysteresis voltage can be selected from the range 0.1 V to 0.4 V in 50 mV step.

Overdischarge detection voltage 2.000 V to 3.000 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.

Overcurrent 1 detection voltage 0.050 V to 0.300 V (applicable in 10 mV step) Accuracy: 15 mV

 Overcurrent 2 detection voltage 0.500 V (fixed) Accuracy: 100 mV

(2) High-withstand voltage (VM pin and CO pin: Absolute maximum rating  28 V)

(3) Delay times (overcharge: t_CU, overdischarge: t_DL, overcurrent 1: t_lOV1, overcurrent 2: t_lOV2) 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

3.5 A typ., 7.0 A max.

0.1 A max.

 Power-down mode

(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
