LITHIUM-ION/POLYMER BATTERY PROTECTION IC
DESCRIPTION
6 5 4
UTC UB242 is a series of lithium-ion / lithium-polymer rechargeable battery protection ICs incorporating high accuracy voltage detection circuits and delay circuits.
UTC UB242 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 UB242 into the limited space of battery pack.
