UB211C Description
UTC UB211C is a series of lithium-ion / lithium-polymer rechargeable battery protection ICs incorporating high accuracy voltage detection circuits and delay circuits. UTC UB211C 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 requirement of external ponents make it ideal to integrate the UTC...
