1-CELL LITHIUM-ION/POLYMER

BATTERY PROTECTION IC



DESCRIPTION

The UTC UB261 is a series of lithium-ion/lithium-polymer

rechargeable battery protection ICs incorporating high accuracy

voltage detection circuits and delay circuits.

The UTC UB261 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 UB261 into the limited space of

battery pack.
