MP62341DS-1-LF-Z

Overview

The MP62341DS-1-LF-Z is a dual-channel power distribution switch IC from Monolithic Power Systems, housed in an 8-SOIC package. It operates within a supply voltage range of 2.7 V to 5.5 V and supports a continuous output current of 1 A per channel with a fixed current limit of 1.5 A. The device features a maximum on-resistance of 130 mOhms and includes protection against overcurrent, overtemperature, reverse current, and under-voltage lockout. It utilizes active-high control logic and provides status flags for fault monitoring.

Feature Summary

• Dual-channel high-side power switching with integrated load release functionality
• Comprehensive fault protection including fixed current limiting, thermal shutdown, and reverse current blocking
• Active-high enable interface with open-drain status flag reporting for system monitoring

Applications

• Power distribution networks in industrial equipment
• Peripheral power management in computing systems
• Load switching for communication infrastructure modules

Procurement Notes

Verify the specific suffix -1-LF-Z against official datasheets to confirm pinout and electrical characteristics match design requirements. Confirm RoHS compliance status and moisture sensitivity level before assembly. Check manufacturer lifecycle status as components may be marked Not Recommended for New Designs (NRND). Validate package dimensions against PCB footprint specifications.

Selection Notes

Select this component when dual independent high-side switching with precise current limiting is required within a 5.5 V domain. Ensure the 130 mOhms on-resistance meets thermal dissipation constraints at 1 A loads. Verify that active-high control logic aligns with host microcontroller GPIO capabilities. Consider the SOIC-8 package size for space-constrained layouts requiring surface-mount integration.

Part Context

This part belongs to the MP62341 series of intelligent power switches designed for robust load management. It integrates advanced protection features typically found in higher-cost discrete solutions into a compact monolithic IC. The series targets applications requiring reliable power sequencing and fault isolation in multi-rail systems.

Replacement Considerations
