LITHIUM-ION/POLYMER
BATTERY PROTECTION IC
CMOS 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:
VDD=1.8V~9.0V
* Ultra-low quiescent current:
IDD=3.0μA (VDD=3.9V)
* Ultra-low power-down current:
IPD=0.1μA (VDD=2.0V)
* Overcharge detection voltage:
VOCU=4.200V~4.400V
* Overcharge release voltage:
VOCR=4.005V~4.225V
* Over discharge detection voltage :
VODL=2.15V~3.00V
* Over discharge release voltage:
VODR=2.32V~3.10V
* Over current detection voltage:
VOI1=0.05V~0.20V
* Short circuit detection voltage:
VOI2=1.35V (Fixed)
* Charger detection voltage:
VCH=-0.7V
Reset resistance for over current protection: RSHORT＞500kΩ
* Delay times are generated by an internal circuit.
(External capacitors are unnecessary.)
* Halogen Free
