MP62171ES-LF-P

Overview

The MP62171ES-LF-P is a single-channel power distribution switch from Monolithic Power Systems. It operates within an input voltage range of 3.3V to 5.5V and provides a continuous output current of 1.5A with a 2.3A current limit. The device features a low on-resistance of 130mΩ maximum, ensuring efficient power delivery. It includes integrated load discharge and status flag functionalities for system monitoring. The component supports an On/Off interface and is available in an 8-SOIC package.

Feature Summary

• Integrates active-low output with 1.5A continuous current capability
• Includes built-in load discharge circuitry for safe power-down sequences
• Provides status flag indication for fault or operational monitoring

Applications

• Peripheral power distribution in industrial control systems
• Power sequencing for embedded computing modules
• Protection circuits for high-side load switching applications

Procurement Notes

Verify the specific suffix 'P' against official datasheets to confirm packaging details, as distributors may list variations. Confirm RoHS compliance status directly with the manufacturer documentation. Ensure the source document explicitly identifies this part number as the primary reference for technical specifications.

Selection Notes

Select this component when a single-channel solution with 1.5A capacity is required for 3.3V or 5V systems. The integrated status flag simplifies diagnostic implementation compared to basic switches. Verify that the 130mΩ on-resistance meets thermal requirements for the specific PCB layout and ambient conditions.

Part Context

This part belongs to the MP6217x series of power distribution switches designed for robust load management. It complements other MPS offerings by providing a compact solution for protecting downstream loads. The series typically emphasizes ease of integration and reliable fault protection for standard voltage rails.

Replacement Considerations

Official documentation suggests using MP62550 or MP62551 as replacements. Verify pin compatibility and electrical parameter alignment before substitution. Consult the manufacturer's cross-reference guide for definitive equivalence confirmation.
