LITHIUM-ION/POLYMER

BATTERY PROTECTION IC



DESCRIPTION

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.



FEATURES

* Wide supply voltage range:

* Ultra-low quiescent current:

* Ultra-low power-down current:

* Overcharge detection voltage:

* Overcharge release voltage:

* Over discharge detection voltage :

* Over discharge release voltage:

* Over current detection voltage:

* Short circuit detection voltage:

* Charger detection voltage:

* Delay times are generated by an internal circuit.

(External capacitors are unnecessary.)
