MP2672AGD-0000-Z

Overview

The MP2672AGD-0000-Z is a boost charger IC designed for two-cell series lithium-ion battery packs. It supports an input voltage range of 4.5 V to 6 V and delivers a maximum charging current of 2 A. The device regulates the output to 8.4 V with a supply voltage limit of 5.75 V. It features an I2C interface for programmable control of charge current and timers. The component operates within a junction temperature range of -40°C to 125°C and is housed in an 18-QFN (2x3) package.

Feature Summary

• Integrated boost topology enables charging from low-voltage sources such as USB or single-cell Li-ion batteries.
• I2C-controlled architecture allows dynamic adjustment of charging parameters including current and timing.
• Comprehensive fault protection mechanisms include over-current, over-temperature, over-voltage, reverse battery, and short-circuit safeguards.

Applications

• Two-cell series lithium-ion battery pack management
• Portable electronic devices requiring boost charging capabilities
• Battery-powered systems utilizing I2C-configurable power management

Procurement Notes

Verify the specific suffix code against official Monolithic Power Systems documentation to confirm pinout and functional variations. Ensure compatibility with the target PCB footprint, specifically the 18-QFN (2x3) package dimensions. Confirm that the application circuit supports the required 4.5 V to 6 V input range for proper boost operation.

Selection Notes

Select this component when designing systems with two-series lithium-ion cells requiring charging from inputs lower than the battery stack voltage. The I2C interface is suitable for applications needing software-defined charge profiles. Verify that the 2 A current rating meets the system's power requirements and thermal constraints.
