BATTERY PROTECTION IC
CMOS 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.
