MP2651GVT-040A-Z

Overview

The MP2651GVT-040A-Z is an I2C-controlled buck-boost battery charger designed for 1 to 4 series Li-ion, Li-polymer, and LiFePO4 battery packs. It features a reverse source mode for USB On-The-Go (OTG) functionality. The device supports NVDC power path management to prioritize system load while charging the battery. It operates within a wide input voltage range of 4V to 21V and utilizes a 30-TQFN package.

Feature Summary

• I2C-controlled buck-boost architecture supporting 1S to 4S battery configurations
• Reverse source mode enabling USB OTG capability for host device operation
• Integrated NVDC power path management for efficient system power distribution

Applications

• Portable devices requiring USB OTG host functionality
• Multi-cell lithium-ion battery pack management systems
• Li-polymer battery applications with strict power path requirements
• LiFePO4 battery charging solutions

Procurement Notes

Verify the specific suffix '040A' against official Monolithic Power Systems documentation to confirm factory default settings for 4-cell applications. Ensure compatibility with required I2C addressing and check for moisture sensitivity labeling on packaging. Confirm that the 30-TQFN footprint matches the target PCB design before procurement.

Selection Notes

Select this component when designing systems requiring bidirectional power flow via USB OTG alongside standard charging capabilities. It is suitable for applications needing precise I2C control over charging parameters. Consider the 4V to 21V input range for flexibility in adapter selection. Verify thermal performance requirements for the TQFN package in the final enclosure design.

Part Context

This part belongs to the MPS MP2651 family of battery chargers. It is specifically engineered for multi-cell series battery packs. The device integrates high-efficiency switching regulators and power path controllers. It serves as a comprehensive solution for portable electronics requiring robust battery management and host connectivity features.

Replacement Considerations

Check MPS datasheets for direct pin-compatible alternatives within the MP265x series. Verify if other suffixes offer different default configurations or enhanced features. Ensure any substitute maintains support for 1S to 4S configurations and reverse source mode if these are critical requirements.
