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.
