Single Cell Lithium-Ion Battery Protection Circuit  
FEATURES  
DESCRIPTION  
Protects Sensitive Lithium-Ion Cells Form  
Over Charging and Over Discharging  
UCC3958 is a monolithic BCMOS lithium-ion battery protection  
circuit that is designed to enhance the useful operating life of  
one cell rechargeable battery packs. Cell protection features  
consist of internally trimmed charge and discharge voltage lim-  
its, discharge current limit with a delayed shutdown and an ultra  
low current sleep mode state when the cell is discharged. Addi-  
tional 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 circuit requires a minimum number of ex-  
ternal components and is able to operate and safely shutdown  
in the presence of a short circuit load.  
Dedicated for One Cell Applications  
Does Not Require External FETs or Sense  
Resistors  
Internal Precision Trimmed Charge and  
Discharge Voltage Limits  
Extremely Low Power Drain  
Low FET Switch Voltage Drop of 150mV  
Typical for 3A Currents  
Short Circuit Current Protection (with User  
Programmable Delay)  
3A Current Capacity  
Thermal Shutdown  
User Controlled Enable Pin
