1-CELL LITHIUM-ION/POLYMER
BATTERY PROTECTION IC
DESCRIPTION
The UTC UB291 is a series of lithium-ion/lithium-polymer
rechargeable battery protection ICs incorporating high accuracy
voltage detection circuits and delay circuits.
The UTC UB291 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 UB291 into the limited space of
battery pack.
