The MC33349 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, charge and discharge current limit detection,
and a virtually zero current sleepmode state when the cell is discharged.
This protection circuit requires a minimum number of external components
and is targeted for inclusion within the battery pack. This MC33349 is
available in the SOT–23 6 lead surface mount package.
