Preliminary
LITHIUM-ION/POLYMER BATTERY PROTECTION IC
DESCRIPTION
The UTC UB24205 is a lithium-ion / lithium-polymer rechargeable battery protection IC with internal
MOSFETs. It incorporates high accuracy
voltage detection circuits and delay circuits.
The UTC UB24205 is suitable for protection of single cell lithium-ion / lithium polymer battery packs from overcharge, over discharge and over current.
The small package and less required external components make it ideal to be integrated into limited space of battery pack.
FEATURES
