MP2676EG-LF-P

Overview

The MP2676EG-LF-P is a single-cell lithium-ion battery charger IC manufactured by Monolithic Power Systems. It integrates a power MOSFET, input current limit, thermal regulation, and an NTC thermistor for safe charging management. The device supports standard CC/CV charging profiles with programmable charge current and termination voltage. It operates from a 4.5 V to 10 V input supply and includes status flags, charge timer, and automatic recharge functions.

Feature Summary

• Integrates a high-efficiency synchronous step-down converter topology for single-cell Li-ion battery charging
• Includes built-in thermal regulation to reduce charge current when die temperature reaches a predefined threshold
• Features an NTC pin for external thermistor monitoring to ensure safe operation across varying temperatures
• Provides programmable charge current and termination voltage via external resistors

Applications

• Portable consumer electronics such as smartphones and tablets
• Wearable devices requiring compact single-cell power solutions
• Handheld medical instruments
• IoT sensors and modules

Procurement Notes

Verify the exact suffix against official MPS documentation to confirm package type and tape/reel specifications. Ensure compatibility with your PCB footprint and thermal design requirements. Confirm RoHS compliance status through the manufacturer's datasheet or environmental declaration before procurement.

Selection Notes

Select this component for applications requiring a compact, integrated solution for single-cell lithium-ion batteries. Consider the QFN-8 package size and operating temperature range relative to your system constraints. Evaluate the need for external components like the NTC thermistor and programming resistors during the design phase.
