MP2651GVT-000A-Z

Overview

The MP2651GVT-000A-Z is an I2C-controlled buck-boost battery charger from Monolithic Power Systems. It supports 1S to 4S lithium-ion battery packs and delivers up to 6 A of output current. The operating supply voltage range spans from 4 V to 22 V. This component integrates NVDC power path management and USB OTG source mode capabilities. It is housed in a QFN-30 package suitable for surface mount installation.

Feature Summary

• I2C interface for digital control and monitoring
• Buck-boost topology supporting single-cell to four-cell configurations
• Integrated NVDC power path management
• USB On-The-Go (OTG) source mode capability

Applications

• Portable electronic devices requiring multi-cell battery support
• Systems utilizing USB Power Delivery (PD) standards
• Applications necessitating USB OTG functionality
• Battery management systems with digital control requirements

Procurement Notes

Verify the specific suffix -000A-Z against official datasheets to confirm factory default settings, as these often dictate initial configuration parameters such as cell count targets. Ensure compatibility with the host controller's I2C protocol. Confirm package dimensions match the PCB footprint design. Check for moisture sensitivity level requirements during storage and handling procedures.

Selection Notes

Select this component when designing systems that require flexible input voltage ranges compatible with buck-boost operation. It is appropriate for applications needing high charging currents up to 6 A. Consider the I2C interface if digital regulation and status reporting are required. Evaluate the QFN-30 package constraints regarding thermal dissipation and board space availability.

Part Context

This part belongs to the MP2651 series of battery charge management ICs. It is designed by Monolithic Power Systems for advanced power management in portable electronics.
