description  
DP PACKAGE  
(TOP VIEW)  
The UCC3952 monolithic BiCMOS lithium–ion  
battery protection circuit increases the useful  
operating life of a one-cell rechargeable battery  
pack. Cell protection features include 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 discharged. Additional features include  
an on-chip MOSFET for reduced external compo-  
nent count and a charge pump for reduced power  
losses while charging or discharging a low-cell-  
voltage battery pack. This protection circuit  
requires one external capacitor and can operate  
and safely shut down in a short circuit condition.
