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.


