MP2607DL-LF-P

Overview

The MP2607DL-LF-P is a highly integrated single-cell lithium-ion or lithium-polymer battery charger manufactured by Monolithic Power Systems. It features an integrated system power path management function, allowing the system to be powered via AC adapter or USB interface while simultaneously charging the battery. The device supports trickle, constant current (CC), and constant voltage (CV) charging modes with automatic termination. It includes a low-dropout regulator from input to system and a 50mΩ switch from battery to system for efficient power routing.

Feature Summary

• Integrates complete system power path management to automatically select power sources between input, battery, or both for continuous system operation.
• Supports full-charge automation including trickle, constant current, and constant voltage regulation with built-in charge termination timers.
• Eliminates the need for external reverse blocking diodes through internal circuitry design.
• Provides comprehensive protection features including input overvoltage protection and thermal regulation.

Applications

• Portable electronic devices requiring simultaneous operation and charging
• Single-cell lithium-ion battery systems in consumer electronics
• USB-powered applications with integrated battery backup
• AC adapter powered devices with battery retention capabilities

Procurement Notes

Verify the specific suffix 'DL' against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the ordering part number with the manufacturer's latest documentation to avoid discrepancies in package type or temperature rating before finalizing procurement.

Selection Notes

Select this component when designing systems that require seamless power transition between an external source and a single-cell battery without external diodes. It is suitable for applications needing precise voltage regulation and integrated thermal management. Consider the QFN14 package dimensions for PCB layout constraints and ensure the input voltage range matches the available power supply infrastructure.

Part Context
