MP2637GR-Z

Overview

The MP2637GR-Z is a high-integration single-cell switching battery charger from Monolithic Power Systems, designed for lithium-ion and lithium-polymer batteries. It operates within a 4.5 V to 6 V input voltage range and supports up to 2.5 A adjustable charging current. The device features integrated power-path management, prioritizing system power while charging the battery. In boost mode, it delivers up to 2.4 A system output current. Key electrical parameters include a QFN-24 package, operation temperatures from -40°C to +125°C, and a quiescent current of 2.5 mA.

Feature Summary

• Integrated power-path management automatically balances system load and battery charging requirements
• Supports reverse boost operation to supply system power when input source is disconnected
• Includes comprehensive safety protections such as over-temperature shutdown and short-circuit protection

Applications

• Single-cell lithium-ion battery powered portable devices
• Lithium-polymer battery managed consumer electronics
• Systems requiring combined charging and system power distribution

Procurement Notes

Verify the specific suffix Z indicates reel packaging configuration against official MPS documentation. Confirm RoHS compliance status through the manufacturer's certified datasheet. Ensure the QFN-24 footprint matches your PCB layout requirements. Cross-reference the part number with authorized distributors to validate authenticity and supply chain integrity before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring a single-chip solution for both battery charging and system power path management. It is suitable for designs needing up to 2.5 A charging capability and 2.4 A boost output. Consider the QFN-24 package size for space-constrained layouts. Verify that the input voltage range aligns with your available power sources and that thermal management supports the specified operating temperature range.

Part Context

This component belongs to the MP2637 series of battery management ICs from Monolithic Power Systems. It is part of a family of high-integration chargers designed for portable electronics. The GR-Z designation specifies the tape-and-reel packaging format. It shares functional similarities with other MPS single-cell chargers but offers specific current ratings and feature sets defined by its unique datasheet specifications.

Replacement Considerations

MP2637GR-P is a verified alternative offering identical functionality in cut-tape packaging.
