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
Absolute maximum rating of 30V for the charger connection pins(VM and CO)
Highly accurate voltage detector………….Overcharge detection (Topt=+25°C)
(Topt=-5 to 55°C)
Overcharge hysteresis
Overdischarge detection
Overcurrent 1 detection
Overcurrent 2 detection
Variety of detector………………………… Overcharge detection
Overcharge hysteresis
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.

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.
0V-battery charge option: Acceptable/Unacceptable.
Low current consumption
Operation: 3.0µA typ. 6µA max.
Power-down 0.1µA max.
DP pin……………………………………...At V
SS
level, delay circuit is disabled. Tie a 300kΩ resistor to V
SS,
delay time of all items expect short-circuit can be reduced.
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
Lithium-ion rechargeable battery packs.
Lithium polymer rechargeable battery packs.
