MP6231DN-LF-Z

Overview

The MP6231DN-LF-Z is a dual-channel power distribution switch manufactured by Monolithic Power Systems. It operates with an active high enable input and supports supply voltages from 2.7 V to 5.5 V. Each channel provides a maximum output current of 500 mA with a typical current limit of 650 mA. The device features a maximum on-resistance of 130 mΩ, ensuring efficient power delivery. It includes thermal shutdown protection and operates within a temperature range of -20°C to +85°C.

Feature Summary

• Dual-channel architecture for independent load control
• Active high logic interface for easy integration
• Integrated current limiting and thermal protection

Applications

• Power distribution in embedded systems
• Load switching for peripheral devices
• Battery-powered equipment management

Procurement Notes

Verify the specific suffix LF-Z confirms lead-free compliance and RoHS status against the manufacturer's latest documentation. Confirm the SOIC-EP-8 package dimensions match your PCB footprint requirements. Ensure design compatibility with the specified 2.7 V to 5.5 V operating voltage range before finalizing procurement.

Selection Notes

Select this component when dual-channel isolation is required within a compact surface-mount form factor. The low on-resistance minimizes power loss during conduction. Verify that the 500 mA per-channel rating meets the peak load demands of the connected peripherals without triggering current limit thresholds under normal operation.

Part Context

This part belongs to the MPS power distribution switch family, designed for managing multiple loads in space-constrained applications. It serves as a robust alternative to discrete MOSFET solutions, offering integrated protection features in a standardized package suitable for consumer and industrial electronics.

Replacement Considerations

Check for direct pin-compatible alternatives within the same MPS series or other manufacturers offering dual-channel current-limited switches with similar voltage and current ratings. Ensure thermal performance and package outline compatibility are maintained during substitution.
