MP2650GV-0400-P

Overview

The MP2650GV-0400-P is an I2C-controlled battery charger IC from Monolithic Power Systems designed for 2S to 4S lithium-ion battery packs. It supports both buck and boost charging topologies with a maximum output current of 5A and a programmable charge voltage up to 18V. The device operates on a supply voltage range of 4V to 21V and integrates NVDC power path management alongside USB OTG functionality. Housed in a compact 30-QFN (4x5mm) package, it features comprehensive fault protection including over-current, over-temperature, over-voltage, under-voltage, and short-circuit safeguards.

Feature Summary

• I2C interface enables precise digital control and monitoring of charging parameters
• Integrated NVDC power path management optimizes system power distribution
• Supports USB On-The-Go (OTG) capability for host mode operation
• Buck or boost topology adapts to varying input and battery voltage conditions

Applications

• Portable electronic devices requiring 2S to 4S battery configurations
• Systems utilizing USB OTG for peripheral connectivity
• Applications demanding integrated power path management
• Battery-powered equipment requiring I2C-configurable charging profiles

Procurement Notes

Verify the specific suffix 'P' against official MPS documentation to confirm packaging type and availability status. Confirm that the '0400' designation aligns with your required electrical specifications. Check regional distributor stock as availability may vary. Ensure compatibility with your I2C bus voltage levels and thermal requirements for the QFN-30 package.

Selection Notes

Select this component when designing systems with 2S to 4S lithium-ion batteries requiring flexible buck/boost charging. It is suitable for applications needing USB OTG support and centralized power management via I2C. Consider the 30-QFN package for space-constrained designs. Verify that the 5A current rating meets peak load requirements and that the 4V-21V input range matches your source capabilities.

Part Context

This part belongs to the MP2650 series of battery management ICs from Monolithic Power Systems. The series focuses on providing integrated charging solutions with advanced power path management for multi-cell battery packs. The MP2650 variant specifically targets applications requiring high flexibility in charging topology and digital control interfaces.

Replacement Considerations

MP2650GV-0000-Z is listed as a direct substitute by distributors. Verify functional equivalence and pinout compatibility before substitution. Ensure any alternative maintains the same I2C address and register map if software integration is already established.
