LITHIUM BATTERY  
PROTECTION CIRCUIT  
FOR  
ONE CELL  
SMART BATTERY PACKS  
The MC33348 is a monolithic lithium battery protection circuit that is  
designed to enhance the useful operating life of a one cell rechargeable  
battery pack. Cell protection features consist of internally trimmed charge  
and discharge voltage limits, discharge current limit detection with a  
delayed shutdown, and a virtually zero current sleepmode state when the  
cell is discharged. An additional feature includes an on–chip charge pump  
for reduced MOSFET losses while charging or discharging a low cell  
voltage battery pack. This protection circuit requires a minimum number of  
external components and is targeted for inclusion within the battery pack.  
This MC33348 is available in standard SOIC 8 lead surface mount  
package.
