MP62131ES-LF-P

Overview

The MP62131ES-LF-P is a single-channel power distribution switch manufactured by Monolithic Power Systems. It operates within a supply voltage range of 2.7 V to 5.5 V and supports an output current of 500 mA with a fixed current limit of 650 mA. The device features a maximum on-resistance of 130 mΩ and utilizes an active-high control input. It is housed in an 8-pin SOIC package and functions as a power supply support circuit. The component is rated for operation between -20°C and +85°C, providing overcurrent protection and load switching capabilities for low-voltage applications.

Feature Summary

• Integrates a high-side power switch with built-in current limiting for load protection
• Features active-high logic control for straightforward interface with digital systems
• Provides low on-resistance to minimize conduction losses during operation

Applications

• Power distribution in portable electronic devices
• Load switching for peripheral circuits in consumer electronics
• Overcurrent protection in industrial control modules

Procurement Notes

Verify the specific suffix designation carefully, as the provided model uses LF-P while official documentation references LF-Z. Confirm RoHS compliance status and lead-free certification directly with the manufacturer or authorized distributors. Ensure the procurement channel supplies genuine components matching the exact part number to avoid functional discrepancies due to packaging or revision differences.

Selection Notes

Select this component when a single-channel, low-voltage power switch with integrated current limiting is required. It is suitable for applications needing a compact solution for protecting loads up to 500 mA. Consider the 130 mΩ on-resistance for thermal management and the 2.7 V to 5.5 V operating range for compatibility with standard logic levels. Evaluate the SOIC-8 package constraints against available board space.

Part Context

This device belongs to the MP6213x series of power distribution switches from Monolithic Power Systems. These ICs are designed to replace discrete MOSFET and fuse combinations, offering a compact footprint for power management tasks. The series typically includes variants with different current ratings and packages, serving as fundamental building blocks for power routing in modern electronic systems.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Consult the manufacturer's datasheet for recommended alternatives or updated designations, as the component may be marked as Not Recommended for New Designs (NRND). Verify pinout and electrical specifications before considering any generic equivalents.
