MP62171ES-1-LF

Overview

The MP62171ES-1-LF is a single-channel high-side power distribution switch from Monolithic Power Systems. It operates within a voltage range of 2.7 V to 5.5 V and supports a continuous output current of 1.5 A with a 2.3 A current limit. The device features a typical on-resistance of 75 mOhms and a maximum resistance of 130 mOhms. It includes active-low control logic, a maximum turn-on time of 3 ms, and a maximum idle time of 10 ms. The component functions across an operating temperature range of -20°C to +85°C.

Feature Summary

Integrates a single high-side power switch with active-low control interface for simplified system management.
Provides robust overcurrent protection through a defined 2.3 A current limit threshold.
Ensures low power loss via optimized on-resistance characteristics in the SOIC-8 package.

Applications

Peripheral power distribution in embedded systems
Load switching for USB ports and peripheral interfaces
Power sequencing in industrial control modules

Procurement Notes

Verify the specific suffix (LF-Z or LF-P) against the official datasheet to confirm lead-free status and tape-and-reel packaging specifications. Confirm that the active-low control logic aligns with the host microcontroller's output voltage levels. Ensure the thermal performance of the SOIC-8 package meets the requirements for the intended ambient operating conditions.

Selection Notes

Select this component when a single-channel high-side switch with a 1.5 A continuous rating is required. The 2.7 V to 5.5 V input range suits 3.3 V and 5 V systems. Consider the 75 mOhm typical on-resistance for efficiency needs. Verify that the active-low control polarity matches the system design constraints before finalizing the selection.

Part Context

This part belongs to the MP621xx series of power distribution switches from Monolithic Power Systems. These components are designed for efficient load management in portable and industrial electronics. The MP62171 variant specifically offers a 1.5 A current capacity, distinguishing it from higher or lower current options within the same family architecture.
