MP2690GR-P

Overview

The MP2690GR-P is a fully integrated switching battery charger IC designed for single-cell lithium-ion or lithium-polymer batteries. It features system power path management, allowing simultaneous charging and system operation. The device supports up to 2.5A programmable charging current and provides up to 2.1A boost output current when the input source is disconnected. Key electrical parameters include an operating input voltage range of 4.65V to 6V (tolerant up to 14V), selectable charge voltages of 4.2V, 4.35V, or 4.45V with 0.5% accuracy, and a QFN-26 (4x4mm) package.

Feature Summary

• Integrates IN-to-SYS pass-through path with overvoltage and overcurrent protection for prioritized system power delivery.
• Supports three-stage charging profiles including trickle, constant current, and constant voltage modes with automatic recharge functionality.
• Features integrated LED drivers for battery status indication and flashlight control capabilities.
• Includes comprehensive protection mechanisms such as thermal regulation, NTC monitoring, and reverse boost short-circuit protection.

Applications

• Portable consumer electronics powered by single-cell Li-ion or Li-Po batteries
• Devices requiring combined charging and boost power path management
• Applications utilizing LED indicators for battery level visualization

Procurement Notes

Verify the specific suffix GR-P against official Monolithic Power Systems documentation to confirm pinout and packaging specifications. Ensure compatibility with the required charge voltage setting (4.2V/4.35V/4.45V) during design implementation. Cross-reference the QFN-26 footprint dimensions with your PCB layout guidelines to ensure accurate assembly.

Selection Notes

Select this component for designs requiring a compact solution that combines battery charging with system power distribution. It is suitable for applications needing high efficiency in both charging and boost modes. Consider the thermal performance within the 4x4mm QFN package relative to the expected load currents and ambient operating conditions.
