LITHIUM BATTERY PROTECTION CIRCUIT FOR ONE CELL SMART BATTERY PACKS

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.
