MP6211DN-LF

Overview

The MP6211DN-LF-Z is a single-channel power distribution switch from Monolithic Power Systems. It operates with an active-high enable input and supports a supply voltage range of 4.5 V to 5.5 V. The device provides a maximum output current of 1 A and features a fixed current limit of 1.5 A to protect against overload conditions. Key electrical parameters include a maximum on-resistance of 80 mΩ, a maximum turn-on time of 10 ms, and a maximum blanking time of 3 ms. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates internal current limiting to prevent damage to host devices during faulty load conditions
• Features active-high logic control for straightforward interface with system controllers
• Provides overcurrent protection through fixed current limit threshold

Applications

• Power distribution in portable electronic devices
• Load switching in consumer electronics
• Peripheral power management in industrial systems

Procurement Notes

Verify the specific suffix (e.g., LF-Z) to confirm lead-free compliance and tape-and-reel packaging details. Confirm the active status as some listings may indicate Not Recommended for New Design (NRND) status. Ensure the SOIC-8 package variant matches your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when a single-channel, 1 A rated power switch with integrated current limiting is required. It is suitable for applications operating strictly within the 4.5 V to 5.5 V supply range. Consider alternative MPS models if higher current capacity or different voltage ranges are needed.

Part Context

This part belongs to the MPS MP621x series of power distribution switches. These ICs are designed to replace discrete MOSFET solutions, offering compact integration of switching and protection functions in small surface-mount packages like SOIC-8.

Replacement Considerations

Check for direct pin-compatible alternatives within the MPS portfolio. Verify that substitute parts maintain the same 1 A output current rating and 80 mΩ on-resistance specifications to ensure circuit compatibility.
