MP62181DH-LF-P

Overview

The MP62181DH-LF-P is a single-channel power distribution switch from Monolithic Power Systems. It operates with an active high enable input and supports supply voltages between 2.7 V and 5.5 V. The device provides a continuous output current of 2 A with a typical on-resistance of 130 mΩ. It features a 2.8 A current limit, 10 ms turn-on time, and 3 ms idle time. Operating temperatures range from -40°C to +85°C in an 8-MSOP package.

Feature Summary

• Integrates a single low-side power switch with active-high control logic for simplified interface.
• Includes internal current limiting to protect against overload conditions during operation.
• Provides controlled turn-on timing to minimize inrush currents when powering loads.

Applications

• Power distribution in embedded systems requiring 3.3V or 5V rails
• Peripheral power switching in industrial control equipment
• Load protection in automotive infotainment modules

Procurement Notes

Verify the specific suffix DH-LF-P against the manufacturer datasheet to confirm pinout and thermal pad configuration. Confirm RoHS compliance status as required by project specifications. Check for end-of-life notifications such as NRND status before finalizing procurement plans to ensure long-term availability.

Selection Notes

Select this component when a single-channel switch with 2A capacity is needed for 5V systems. Ensure the application requires active-high logic control. Verify that the 130 mΩ on-resistance meets thermal requirements for the expected load current within the specified operating temperature range.

Part Context

This part belongs to the MP6218x series of power distribution switches. It shares functional similarities with the MP62180 but differs in control logic polarity. The MP62181 series is designed for general-purpose power switching applications where compact packaging and integrated protection are prioritized over multi-channel integration.

Replacement Considerations

The MP62180DS-LF-Z is a related variant within the same family. Verify if the active-low control requirement of the MP62180 is compatible with the system design, as it differs from the active-high logic of the MP62181.
