UB262 Datasheet

1-CELL LITHIUM-ION/POLYMER BATTERY PROTECTION IC
 


DESCRIPTION
 
 
The UTC UB262 is a series of lithium-ion / lithium-polymer
rechargeable battery protection ICs incorporating high accuracy
voltage detection circuits and delay circuits.
The UTC UB262 is suitable for protection of single cell lithium-ion /
lithium polymer battery packs from overcharge, over discharge and
over current.
The ultra-small package and less required external components
make it ideal to integrate the UTC UB262 into the limited space of
battery pack.
 
 
 
 
FEATURES
* High-accuracy voltage detection circuit
Overcharge detection voltage: 4.250~4.350V, Accuracy: ±50Mv
Overcharge release voltage: 4.050~4.150V, Accuracy: ±50mV
Overdischarge detection voltage: 2.30~2.90V, Accuracy: ±100mV
Overdischarge release voltage: 2.90~3.00V, Accuracy: ±100mV
Discharge overcurrent detection voltage: 150mV, Accuracy: ±30mV
Short-circuiting detection voltage: 0.85V (fixed), Accuracy: ±300mV
* Delay times are generated by an internal circuit (external capacitors are unnecessary)
Overcharge delay time: 100ms (typ.)
Overdischarge delay time: 25ms (typ.)
Discharg e overcurrent delay time: 10ms (typ.)
Short circuit delay time: 500μs (typ.)
