EUP9261  
LI-ION/POLYMER ONE CELL PROTECTOR  
DESCRIPTION  
The EUP9261 series are lithium-ion/lithium polymer rechargeable battery protection ICs incorporating  
high-accuracy voltage detection circuit and delay circuit. The EUP9261 series are suitable for protection of  
single-cell lithium-ion/lithium polymer battery packs from overcharge, overdischarge and overcurrent.  
FEATURES  
z
Absolute maximum rating of 30V for the charger connection pins(VM and CO)  
Highly accurate voltage detector………….Overcharge detection (Topt=+25°C)  
z
±25mV  
±30mV  
±25mV  
±50mV  
±15mV  
±100mV  
(Topt=-5 to 55°C)  
Overcharge hysteresis  
Overdischarge detection  
Overcurrent 1 detection  
Overcurrent 2 detection  
z
Variety of detector………………………… Overcharge detection  
Overcharge hysteresis  
3.9V-4.4V step of 5mV  
0.0V-0.4V*1 step of 50mV  
2.0V-3.0V step of 10mV  
0.0V-0.7V*2 step of 100mV  
0.03V-0.3V step of 10mV  
0.5V  
Overdischarge detection  
Overdischarge hysteresis  
Overcurrent 1 detection  
Overcurrent 2 detection  
*1 Overcharge release voltage=Over detection voltage-Overcharge hysteresis voltage  
*2 Overdischarge release voltage = Overdischarge detection voltage-Overdischarge hysteresis voltage.  
z
Delay times internally generated. Accuracy : ±30%.  
(overcharge: tCU, overdischarge: tDL, overcurrent 1: tlOV1, overcurrent 2: tlOV2  
)
z
z
Three-step overcurrent detection circuit is included.(overcurrent 1,overcurrent 2 and load short – circuiting)  
Charger detection function and abnormal charge current detection function, included.  
z
z
0V-battery charge option: Acceptable/Unacceptable.  
Low current consumption  
„ Operation: 3.0µA typ. 6µA max.  
„ Power-down 0.1µA max.  
z
DP pin……………………………………...At VSS level, delay circuit is disabled. Tie a 300kΩ resistor to VSS,  
delay time of all items expect short-circuit can be reduced.  
z
z
z
Wide operating temperature range: -40°C to + 85°C.  
Small package: SOT-23-6, STDFN-6(2mm*2mm)  
RoHS compliant and 100% lead (Pb)-free  
APPLICATIONS  
z Lithium-ion rechargeable battery packs.  
z Lithium polymer rechargeable battery packs.
