MP2720AGRH-0000-Z

Overview

The MP2720AGRH-0000-Z is a single-cell buck charger IC designed for lithium-ion and lithium-polymer batteries. It supports a maximum charging current of 2.2A and operates with an input voltage range up to 6.3V. The device features a 22-QFN (2.5x3.5mm) package and includes I2C interface capabilities for programmable control of current, timer, and voltage parameters. It provides overcurrent and overvoltage fault protection and functions within a junction temperature range of -40°C to +125°C.

Feature Summary

• Integrates I2C interface for programmable charging parameters including current, timer, and voltage settings.
• Includes built-in overcurrent and overvoltage fault protection mechanisms for enhanced system safety.
• Supports surface-mount installation in a compact 22-QFN package suitable for space-constrained designs.

Applications

• Single-cell lithium-ion battery charging systems
• Lithium-polymer battery management applications
• Portable electronic devices requiring programmable charge profiles

Procurement Notes

Verify the specific suffix against official Monolithic Power Systems documentation to confirm exact packaging and tape-and-reel specifications. Ensure compatibility with I2C bus requirements and thermal management needs for the 22-QFN package. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement orders.

Selection Notes

Select this component for applications requiring precise control over single-cell Li-ion or Li-Po charging cycles via digital interface. The 2.2A capability suits moderate-power portable electronics. Evaluate thermal dissipation requirements given the QFN package size and operating temperature range when designing the PCB layout.

Part Context

This part belongs to the MPS battery charger family, specifically targeting single-cell chemistries. It differs from multi-cell chargers and linear regulators by offering switching efficiency and digital configurability. The GRH suffix typically denotes the specific package variant and environmental compliance level defined by the manufacturer.

Replacement Considerations

The MP2720AGRH-0000-P is listed as an alternative part number from the same manufacturer. Verify pinout compatibility and electrical parameter equivalence before substitution. Cross-reference datasheets to ensure functional parity regarding I2C addressing and protection thresholds.
