MP2651GVT-010A-Z

Overview

The MP2651GVT-010A-Z is an I2C-controlled battery charger IC from Monolithic Power Systems, designed for 1 to 4-cell lithium-ion battery packs. It features a buck-boost topology with a wide operating supply voltage range of 4 V to 22 V and supports up to 6 A output current. The device integrates NVDC power path management and reverse source mode capabilities. Factory default configuration (-010A) targets 1-cell applications. It is housed in a QFN-30 package suitable for surface mount installation.

Feature Summary

• I2C-controlled buck-boost charging architecture supporting 1S to 4S battery configurations
• Integrated NVDC power path management for seamless system power distribution
• Reverse source mode functionality enabling USB OTG operations
• Wide input voltage compatibility ranging from 4 V to 22 V

Applications

• Portable electronic devices requiring 1-cell lithium-ion battery charging
• Systems utilizing USB On-The-Go (OTG) peripheral power sourcing
• Battery-powered equipment needing NVDC power path management
• Industrial or consumer electronics with 4V to 22V input sources

Procurement Notes

Verify the specific suffix -010A confirms the factory default setting for 1-cell applications as documented. Confirm the QFN-30 package type matches your PCB footprint requirements. Check RoHS compliance status through official manufacturer documentation before integration. Ensure I2C interface compatibility with your host controller. Validate thermal performance within the specified operating temperature range during design.

Selection Notes

Select this component when designing systems requiring a single-chip solution for 1 to 4-cell lithium-ion batteries with high input voltage tolerance. The integrated reverse source mode is critical for applications needing USB OTG support without additional circuitry. Choose based on the need for I2C configurability to optimize charging profiles dynamically. Consider the QFN-30 package for compact board space constraints compared to larger alternatives.

Part Context

This part belongs to the MP2651 series of battery chargers from Monolithic Power Systems. It shares architectural similarities with the MP2650 but offers enhanced buck-boost capabilities and reverse source mode. The -010A suffix specifically denotes the factory default configuration optimized for 1-cell applications, distinguishing it from variants configured for higher cell counts like the -0400 series.

Replacement Considerations

MP2651GVT-010A-P is listed as a parametric equivalent variant. Verify pinout and electrical specifications against the datasheet before substitution. Other family members like MP2650 lack reverse source mode and may not be direct replacements for OTG applications.
