MP2637GR-P

Overview

The MP2637GR-P is a high-integration, flexible single-cell switching battery charger from Monolithic Power Systems. It supports Lithium-ion and Lithium Polymer batteries with an operating input voltage range of 4.5 V to 6 V. The device delivers a programmable charging current up to 2.5 A and provides a system boost current of 2.4 A. It features integrated power-path management, allowing seamless transition between charging and boost modes. The component operates within a temperature range of -40°C to +125°C and is housed in a QFN-24 package.

Feature Summary

• Integrates power-path management to prioritize system power needs while charging the battery
• Supports reverse boost operation to supply system load directly from the battery when input power is absent
• Includes comprehensive safety mechanisms such as over-temperature shutdown, input over-voltage protection, and battery reverse leakage blocking

Applications

• Single-cell lithium-ion or lithium polymer battery powered portable devices
• Systems requiring simultaneous charging and system power delivery via power-path management
• Applications needing backup power supply through boost mode during input power loss

Procurement Notes

Verify the specific suffix GR-P against official MPS documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with required thermal dissipation standards for the QFN-24 footprint. Cross-reference RoHS compliance status using the manufacturer's latest environmental declarations before finalizing procurement orders.

Selection Notes

Select this component for designs requiring a single-chip solution for both battery charging and system power management. It is suitable for applications where input power availability fluctuates, necessitating automatic switching between charge and boost modes. Consider the 2.5A charging capability and 2.4A boost output when sizing external components and thermal solutions.
