MC33349 Datasheet, PDF (1/12 Pages) ON Semiconductor – Lithium Battery Protection Circuit for One Cell Battery Packs

MC33349
Lithium Battery Protection
Circuit for One Cell
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, discharge
current limit detection, and a low current standby mode when the cell
is discharged. This protection circuit requires a minimum number of
external components and is targeted for inclusion within the battery
pack.
• Internally Trimmed Charge and Discharge Voltage Limits
• Discharge Current Limit Detection
• Low Current Standby Mode when Cells are Discharged
• Dedicated for One Cell Applications
• Minimum Components for Inclusion within the Battery Pack
• Available in a Low Profile Surface Mount Package
