Unisonic Technologies UB2421
UB2421 is a lithium-ion / lithium-polymer rechargeable battery protection IC incorporating high accuracy voltage detection circuits and delay circuits. It is suitable for protection of single cell lithium-ion / lithium polymer battery packs from overcharge, over discharge and over current. The tiny package required external few components make the UTC UB2421 be able to be applied to space limited battery pack.DESCRIPTION
