MP62551DGT-LF-P

Overview

The MP62551DGT-LF-P is a single-channel power distribution switch from Monolithic Power Systems. It operates within a supply voltage range of 2.5 V to 5.5 V and supports an output current of 1.5 A with a current limit of 1.7 A. The device features a maximum on-resistance of 135 mOhms and dissipates up to 1.56 W of power. It includes a maximum run time of 3 ms and an idle time of 30 ms. The component functions in active high mode and is housed in a TQFN-6 surface-mount package, operating between -40°C and +85°C.

Feature Summary

Integrates current limiting protection for load circuits
Provides low on-resistance for efficient power delivery
Includes configurable timing controls for operation cycles

Applications

Power distribution networks
Load switching applications
Portable electronic devices

Procurement Notes

Verify the specific suffix against official MPS documentation to confirm package and tape specifications. The provided model indicates a TQFN-6 package; ensure this matches the target PCB footprint. Confirm RoHS compliance status through the manufacturer's environmental declaration. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement orders.

Selection Notes

Select this component when a single-channel switch with 1.5 A continuous capability is required. The 135 mOhm on-resistance suits low-voltage applications where efficiency is critical. Ensure the input voltage remains within the 2.5 V to 5.5 V range. Consider the thermal dissipation limits if operating near the maximum current threshold in enclosed environments.

Part Context

This part belongs to the MP62551 series of power switches. It complements other MPS offerings like the MP62550 by providing similar functionality in a compact form factor. The series is designed for general-purpose power management tasks requiring reliable load protection and controlled switching behavior in consumer electronics.
