MP2637AGR-Z

Overview

The MP2637AGR-Z is a single-cell switching battery charger from Monolithic Power Systems, designed for lithium-ion and lithium-polymer batteries. It features an integrated power-path management system that prioritizes system power while charging the battery. The device supports a maximum charge current of 2.5A and provides a system boost current of up to 2.4A. It operates with a 5V input voltage and delivers a regulated output voltage of 4.2V. The component is housed in a QFN-24 package and functions within a temperature range of -40°C to +125°C.

Feature Summary

Integrated power-path management automatically balances input power between the system load and battery charging
Supports reverse boost operation to supply system power when external input is disconnected
Includes comprehensive safety protections such as over-temperature shutdown and battery over-voltage protection

Applications

Single-cell lithium-ion battery powered portable devices
Lithium-polymer battery managed systems
Power bank applications requiring OTG functionality

Procurement Notes

Verify the specific suffix Z against the manufacturer datasheet to confirm RoHS compliance and lead time requirements. Confirm the QFN-24 package dimensions match your PCB footprint design. Ensure input voltage sources remain within the specified operational range to maintain proper power-path regulation.

Selection Notes

Select this component for designs requiring simultaneous system power delivery and battery charging without external path switches. It is suitable for applications needing high efficiency during boost mode operation. Consider thermal dissipation capabilities given the power handling characteristics of the QFN-24 package under continuous load conditions.

Part Context

This part belongs to the MP2637A series of highly integrated switch-mode chargers. It shares functional similarities with other MPS battery management ICs but is distinct in its specific 2.5A charge current rating and 2.4A boost capability configuration.
