MP2607DL-LF-Z

Overview

The MP2607DL-LF-Z is a highly integrated single-cell lithium-ion or lithium-polymer battery charger manufactured by Monolithic Power Systems. It features an input voltage range of up to 12V and supports AC adapter or USB power sources. The device includes system power path management, allowing simultaneous system powering and battery charging. Key electrical parameters include a charging voltage accuracy of 0.75%, adjustable charging current, and a 50mΩ switch from battery to system. It operates in a 14-pin QFN package measuring 3mm x 4mm.

Feature Summary

• Integrates system power path management for automatic selection of input, battery, or combined power sources
• Supports AC adapter or USB input with built-in current limiting protection
• Provides complete charge cycle management including trickle, constant current, and constant voltage regulation

Applications

• Single-cell lithium-ion battery charging systems
• Single-cell lithium-polymer battery charging applications
• Portable devices requiring simultaneous system operation and battery charging

Procurement Notes

Verify the specific suffix 'LF-Z' against the manufacturer's latest documentation to confirm lead-free status and packaging type. Confirm availability as distribution channels may vary. Ensure the 14-pin QFN footprint matches the design layout. Check for any obsolescence notices or recommended new designations from Monolithic Power Systems before finalizing procurement.

Selection Notes

Select this component for designs requiring integrated power path management to simplify system power architecture. It is suitable for applications needing precise voltage regulation with 0.75% accuracy. Consider the 3mm x 4mm QFN-14 package constraints for PCB space. Verify that the input source meets the maximum 12V requirement and that the adjustable current settings align with the target battery specifications.

Part Context

This part belongs to the MP2607 series of linear chargers from Monolithic Power Systems. It is designed for single-cell Li-ion and Li-Po batteries. The DL suffix typically denotes the QFN-14 package variant. It integrates low-dropout regulators and switches to manage power distribution efficiently within compact portable electronics.

Replacement Considerations

Consult official MPS documentation for direct pin-compatible substitutes or updated versions within the MP2607 family. Verify functional equivalence regarding power path management and package dimensions if considering alternatives.
