MP2651GVT-030A-Z

Overview

The MP2651GVT-030A-Z is an I2C-controlled buck-boost battery charger from Monolithic Power Systems, designed for 1 to 4-series lithium-ion or polymer battery packs. It features NVDC power path management and reverse source mode capabilities. The device operates with a supply voltage range of 4V to 21V and supports output currents up to 5A. It is housed in a 30-pin QFN package suitable for surface mount installation. The component functions within a temperature range of -40°C to +125°C.

Feature Summary

• I2C-controlled architecture for precise configuration and monitoring
• Buck-boost topology supporting single-cell to four-cell battery configurations
• Integrated NVDC power path management for seamless system operation
• Reverse source mode functionality for USB OTG applications

Applications

• Portable electronic devices requiring multi-cell battery charging
• Systems utilizing USB On-The-Go (OTG) power sharing
• Battery management solutions for consumer electronics
• Industrial equipment with 1S to 4S lithium battery packs

Procurement Notes

Verify the specific suffix '030A' confirms the factory default setting for 3-cell applications as documented by the manufacturer. Ensure compatibility with the required I2C interface and check for any regional sales restrictions or limited availability status before finalizing procurement plans.

Selection Notes

Select this component when designing systems that require flexible input voltage handling via buck-boost conversion for 1 to 4 series batteries. Consider the 30-QFN package size and thermal performance characteristics relative to the expected 5A output current requirements and operating temperature extremes.

Part Context

This part belongs to the MPS MP2651 family of battery chargers. It shares architectural similarities with other models like the MP2650 but offers distinct reverse source mode features. The '030A' designation specifically tailors the internal parameters for optimal performance with three-cell battery stacks.

Replacement Considerations

Direct substitutes include other MPS I2C-controlled buck-boost chargers such as the MP2650 series variants. Verify pinout compatibility and electrical specifications against the MP2761 series if higher cell count support is needed.
