MP62171EK-1-LF-P

Overview

The MP62171EK-1-LF-P is a single-channel power distribution IC manufactured by Monolithic Power Systems. It operates within an input voltage range of 2.7 V to 5.5 V and provides a maximum output current of 1.5 A with a fixed current limit of 2.3 A. The device features a typical on-resistance of 130 mΩ, ensuring efficient power delivery. Key timing parameters include a maximum turn-on time of 3 ms and a maximum idle time of 10 ms. Designed for surface-mount applications, it supports an operating temperature range from -20°C to +85°C.

Feature Summary

• Integrates active-low control logic for precise load switching management
• Provides built-in overcurrent protection with a defined 2.3 A current limit threshold
• Features low on-resistance characteristics to minimize conduction losses during operation

Applications

• Power distribution in portable electronic devices
• Load switching for peripheral modules in consumer electronics
• Battery-powered system power management

Procurement Notes

Verify the specific suffix 'P' against official MPS documentation to confirm packaging configuration, as suffixes often denote tape-and-reel quantities or specific handling requirements. Ensure compatibility with RoHS standards if required by your manufacturing process. Cross-reference the exact part number with authorized distributors to confirm availability and lead times, as supply chain status can vary.

Selection Notes

Select this component when a single-channel high-side switch with integrated current limiting is required for 3.3V or 5V systems. Consider the 1.5A continuous current capability and 2.3A limit for protecting downstream loads. Evaluate the thermal performance based on the 130mΩ resistance and expected ambient temperatures within the -20°C to +85°C operational range.

Part Context

This part belongs to the MP6217 series of power switches from Monolithic Power Systems. These ICs are designed for simple, cost-effective power distribution solutions. The MP62171 variant specifically offers a single channel, distinguishing it from multi-channel counterparts in the family. It serves as a fundamental building block for managing power rails in compact electronic designs.

Replacement Considerations

Consult MPS datasheets for direct pin-to-pin compatible alternatives within the MP6217 series. Verify that any substitute matches the 2.7V-5.5V input range and 1.5A output current specifications. Ensure the replacement maintains similar current limit thresholds and package dimensions for seamless integration.
