描述 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 components make it ideal to integrate the?UTC UB211C into the limited space of battery pack.
