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)
z Highly accurate voltage detector………….Overcharge detection (Topt=+25°C)
(Topt=-5 to 55°C)

z Variety of detector………………………… Overcharge detection
Overcharge hysteresis
3.9V-4.4V step of 5mV
0.0V-0.4V*1 step of 50mV
Overdischarge detection
Overdischarge hysteresis
2.0V-3.0V step of 10mV
0.0V-0.7V*2 step of 100mV
Overcurrent 1 detection
0.03V-0.3V step of 10mV
Overcurrent 2 detection
0.5V
*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 Three-step overcurrent detection circuit is included.(overcurrent 1,overcurrent 2 and load short – circuiting)
z Charger detection function and abnormal charge current detection function, included.
z 0V-battery charge option: Acceptable/Unacceptable.
z 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 300kresistor to VSS,
delay time of all items expect short-circuit can be reduced.
z Wide operating temperature range: -40°C to + 85°C.
z Small package: SOT-23-6, STDFN-6(2mm*2mm)
z RoHS compliant and 100% lead (Pb)-free
APPLICATIONS
z Lithium-ion rechargeable battery packs.
z Lithium polymer rechargeable battery packs.
