MP26028EQ-LF-P

Overview

The MP26028EQ-LF-P is a single-cell lithium-ion battery linear charger from Monolithic Power Systems. It supports an input voltage range of 3.5 V to 5.5 V and delivers a maximum output current of 1 A. The device features a high-voltage input protection capability, tolerating surges up to 28 V. It includes trickle charge functionality, thermal regulation, and status indication pins for AC adapter presence and charging state. The component operates within a temperature range of -40°C to +85°C and is housed in a compact QFN-10 package.

Feature Summary

• Integrates high-voltage surge tolerance up to 28 V for robust input protection
• Provides programmable trickle charge mode for deeply discharged batteries
• Includes thermal regulation to manage power dissipation during charging
• Offers dedicated status indicators for adapter presence and charge completion

Applications

• Portable consumer electronics with USB or AC adapter power sources
• Single-cell lithium-ion battery management systems
• IoT devices requiring efficient linear charging solutions
• Mobile communication equipment with limited space constraints

Procurement Notes

Verify the specific suffix 'EQ' against official MPS documentation to confirm pinout and functional equivalence with standard variants. Ensure the 'P' tape-and-reel packaging matches your assembly line requirements. Cross-reference the RoHS compliance status directly with the manufacturer's latest environmental declarations prior to final procurement approval.

Selection Notes

Select this component when a linear topology is preferred for low noise and simplicity in single-cell applications. Consider the 1 A output current limit and 28 V surge tolerance as key differentiators for harsh input environments. Evaluate the QFN-10 footprint against available PCB real estate. Confirm that the operating temperature range meets the target application's environmental specifications.

Part Context

This part belongs to the MP2602 series of linear chargers designed by Monolithic Power Systems. It shares architectural similarities with models like the MP2602 and MP26023 but may differ in specific package options or minor feature sets. The series targets cost-sensitive, space-constrained portable devices requiring reliable single-cell charging capabilities.

Replacement Considerations

MP2602DQ-LF-P and MP26023DQ-LF-Z are documented members of the same family. Verify pin compatibility and electrical parameter alignment before substitution. No other direct substitutes are confirmed in the provided data.
