MP62171EK-LF-Z

Overview

The MP62171EK-LF-Z is a single-channel power distribution switch IC 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 1.5 A with a hard current limit of 2.3 A. The device features a maximum on-resistance of 130 mΩ, a maximum turn-on time of 3 ms, and a maximum dwell time of 10 ms. It functions as an active-low controlled switch and is rated for operation between -20°C and +85°C in an MSOP-8 package.

Feature Summary

• Integrates a single high-side power switch with active-low control logic for simplified interface design.
• Provides robust overcurrent protection through a fixed 2.3 A current limit threshold to safeguard downstream loads.
• Features low on-resistance to minimize conduction losses and improve thermal efficiency during operation.

Applications

• Power distribution networks requiring single-channel load switching
• Peripheral power management in embedded systems
• Protection circuits for sensitive electronic loads

Procurement Notes

Verify the component status carefully before procurement, as this part number may be classified as Not Recommended for New Designs (NRND). Confirm that the MSOP-8 package dimensions and pinout align with your existing PCB footprint. Ensure the active-low control polarity matches your system's logic levels. Review the latest datasheet for any updates to electrical characteristics or recommended operating conditions prior to finalizing the bill of materials.

Selection Notes

Select this component when a single-channel power switch with active-low control is required. It is suitable for applications needing a 1.5 A continuous output capability with integrated current limiting. Consider the 2.7 V to 5.5 V input range to ensure compatibility with your system voltage rails. The MSOP-8 package offers a compact solution for space-constrained designs. Evaluate the thermal performance based on the 130 mΩ on-resistance under your specific load conditions.

Part Context

This device belongs to the MPS power distribution switch family, designed for efficient power management in portable and industrial electronics. It integrates protection features typically found in discrete solutions into a small surface-mount package. The series focuses on providing reliable load switching with minimal external components, supporting various consumer and industrial applications requiring precise power control.

Replacement Considerations

Check for direct substitutes within the MPS portfolio that share identical pinouts and electrical specifications. Verify if alternative packages are available from other manufacturers if the MSOP-8 form factor can be adapted. Ensure any replacement maintains the active-low control requirement and meets the 1.5 A output current specification.
