S-8261 - BATTERY PROTECTION IC FOR SINGLE-CELL PACK

 
 
Features
(1) Internal high accuracy voltage detection circuit 
Overcharge detection voltage   3.9 V to 4.4 V (applicable in 5 mV step) 
 Accuracy: ±25 mV (+25 °C) and ±30 mV (−5 °C to +55 °C) 
Overcharge hysteresis voltage   0.0 V to 0.4 V
*1
  Accuracy: ±25 mV 
The overcharge hysteresis voltage can be selected from the range 0.0 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. 
Overcurrent 1 detection voltage   0.05 V to 0.3 V (applicable in 10 mV step)  Accuracy: ±15 mV 
Overcurrent 2 detection voltage   0.5 V (fixed)  Accuracy: ±100 mV 
(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: 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” are selectable. 
(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 mode 3.5 µA typ., 7.0 µA max. 
Power-down mode 0.1 µA max. 
(8) Wide operating temperature range   −40 °C to +85 °C 
(9) Small package  SOT-23-6, 6-Pin SNB(B) 
*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.)
