MP26075EQ-41-LF-Z

Overview

The MP26075EQ-41-LF-Z is a high-efficiency linear cradle charger designed for single-cell lithium-ion or lithium-polymer batteries. It operates with an input voltage range of 2.2 V to 6.3 V and provides a fixed output voltage of 4.2 V. The device supports a maximum charge current of 1 A and features a QFN-10 (3mm x 3mm) package. It functions within a temperature range of -20°C to +85°C, with a power dissipation rating of 2.5 W.

Feature Summary

• Controls AC adapter output voltage relative to battery voltage to enhance charging efficiency in cradle applications.
• Provides very low pre-charging current specifically for deeply discharged batteries.
• Manages power-up sequencing by boosting the AC adapter first to suppress surge currents upon insertion.

Applications

• AC adapter-powered cradle chargers
• Single-cell lithium-ion battery charging systems
• Single-cell lithium-polymer battery charging systems

Procurement Notes

Verify component authenticity through authorized MPS distributors or certified suppliers. Confirm the specific suffix LF-Z indicates lead-free compliance and reel packaging format. Ensure the design accommodates the QFN-10 thermal requirements given the 2.5 W power dissipation limit. Check for any regional distribution restrictions or limited availability status before finalizing procurement plans.

Selection Notes

Select this part when designing a linear charging solution for cradle-style applications requiring high efficiency. It is suitable for systems powered directly by AC adapters where input voltages vary between 2.2 V and 6.3 V. Choose this IC if the application demands precise control over power-up timing to prevent surge currents and requires protection against deep discharge conditions.

Part Context

This component belongs to the MP26075 series of high-efficiency linear cradle chargers from Monolithic Power Systems. The series is engineered to optimize energy transfer from AC adapters to single-cell batteries. The EQ-41 variant specifies the 4.2 V output configuration, distinguishing it from other voltage options within the same family.

Replacement Considerations

MP26075EQ-LF-Z serves as a compatible alternative within the same series, offering similar functionality with potentially different factory packaging configurations. Verify that the substitute maintains the required 4.2 V output specification and QFN-10 footprint compatibility.
