Enhanced Single Cell Lithium-Ion Battery Protection IC  
FEATURES  
DESCRIPTION  
Protects sensitive Lithium Ion cells  
from over-charging and  
over-discharging  
The UCC3952 is a monolithic BiCMOS lithium-ion battery protection circuit  
that is designed to enhance the useful operating life of one cell recharge-  
able battery pack. Cell protection features consist of internally trimmed  
charge and discharge voltage limits, discharge current limit with a delayed  
shutdown and an ultra low current sleep mode state when the cell is dis-  
charged. Additional features include an on chip MOSFET for reduced exter-  
nal component count and a charge pump for reduced power losses while  
charging or discharging a low cell voltage battery pack. This protection cir-  
cuit requires one external capacitor and is able to operate and safely shut-  
down in the presence of a short circuit condition.  
Dedicated for one cell applications  
Integrated low impedance MOSFET  
switch and sense resistor  
Precision trimmed overcharge and  
overdischarge voltage limits  
Extremely low power drain  
3A current capacity
