MP2720AGRH-0000-P

Overview

The MP2720AGRH-0000-P is a single-cell switch-mode battery charger IC from Monolithic Power Systems, designed for lithium-ion and lithium-polymer batteries. It features an NVDC buck charging architecture with a maximum output voltage of 4.6 V and a programmable charge current up to 2.5 A. The device operates on a supply voltage range of 3.9 V to 6.3 V and utilizes an I2C interface for configuration. Packaged in a 22-QFN (2.5x3.5 mm) format, it supports surface-mount installation and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates an NVDC power path for seamless system power management during charging
• Supports I2C communication for programmable charge parameters and status monitoring
• Includes built-in protection mechanisms against over-current and over-voltage conditions

Applications

• Single-cell portable electronic devices requiring efficient battery charging
• Consumer electronics utilizing lithium-ion or lithium-polymer battery packs
• Systems necessitating integrated power path management between input source and battery

Procurement Notes

Verify the specific suffix 'A' against official manufacturer documentation to confirm pinout or functional variations compared to standard variants. Ensure compatibility with the required QFN-22 footprint and thermal design constraints. Confirm RoHS compliance status through the latest datasheet before finalizing procurement specifications.

Selection Notes

Select this component when a compact solution for single-cell Li-ion or Li-Po batteries is required. The 2.5 A current capability suits moderate-power applications. The I2C interface allows for flexible system integration and precise control over charging profiles. Verify that the 6.3 V maximum input voltage aligns with the available power source.

Part Context

This part belongs to the MPS MP2720 series of battery chargers. It shares architectural similarities with other members like the MP2721 and MP2724 but differs in specific current ratings and package options. The series focuses on providing efficient, space-saving charging solutions for mobile devices using switch-mode technology.

Replacement Considerations

Consult official substitution lists for verified equivalents. Cross-reference electrical parameters such as charge current limits and operating voltage ranges to ensure functional compatibility without redesigning the power stage.
