MP62171ES-LF-Z

Overview

The MP62171ES-LF-Z 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 features an active low enable input. The device provides a continuous output current of 1.5 A with a hard current limit of 2.3 A. Key electrical specifications include a maximum on-resistance of 130 mOhms, a maximum turn-on time of 3 ms, and a maximum blanking time of 10 ms. It supports surface mount installation in an ESOP-8 package and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates a high-side power switch with active low control logic for efficient load management.
• Includes built-in current limiting protection to safeguard connected loads from overcurrent conditions.
• Features fast switching characteristics with defined turn-on and blanking times for precise timing control.

Applications

• Power distribution networks in embedded systems requiring single-channel load switching
• Protection circuits for peripheral devices in industrial automation equipment
• Load management in automotive electronic control units

Procurement Notes

Verify the specific suffix 'ES' against official Monolithic Power Systems documentation to confirm the exact package type and thermal characteristics. Confirm that the component status aligns with project requirements, as availability may vary. Ensure compatibility with the target PCB footprint and soldering profile before finalizing procurement decisions.

Selection Notes

Select this component when a single-channel load switch with a 1.5 A continuous current rating is required. Consider the 130 mOhm on-resistance for power loss calculations and the 2.3 A current limit for fault protection margins. Verify that the active low enable signal matches the system control logic and that the 2.7 V to 5.5 V supply range fits the application voltage.

Part Context

This part belongs to the MPS power distribution switch family, designed for managing power delivery to individual loads. It serves as a protective interface between the main power source and downstream components, offering compact integration in small outline packages suitable for space-constrained designs.

Replacement Considerations

Consult official MPS cross-reference guides for verified substitutes. Generic equivalents may differ in current limits or package dimensions.
