MP62351ES-LF-Z

Overview

The MP62351ES-LF-Z is a dual-channel power distribution switch IC from Monolithic Power Systems, designed for 3.3V and 5V systems. It features an active-low control type with two independent outputs. The device supports a continuous output current of 500mA per channel, with a peak current limit of 750mA. The maximum on-resistance is specified at 130 mOhms. Operating voltage ranges from 2.7V to 5.5V. The unit includes soft-start functionality with a maximum run time of 3ms and an idle time of 10ms. It operates within a temperature range of -20°C to +85°C and is housed in an SOIC-8 package.

Feature Summary

• Dual-channel architecture providing independent control for two separate power rails
• Active-low logic interface for straightforward system integration
• Integrated current limiting protection to safeguard connected loads
• Controlled turn-on timing via defined soft-start characteristics

Applications

• Power distribution in embedded computing systems
• Peripheral power management in industrial equipment
• Load switching for communication modules
• General-purpose power sequencing in consumer electronics

Procurement Notes

Verify the specific suffix against official MPS documentation to confirm pinout and electrical tolerances, as variations may exist within the MP62351 family. Confirm RoHS compliance status through the manufacturer's certified datasheet rather than distributor summaries. Check the component lifecycle status, as this part may be marked as Not Recommended for New Designs (NRND). Ensure that the SOIC-8 package dimensions match your PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when a dual-channel solution with moderate current capacity is required for low-voltage applications. The 500mA output rating suits most digital logic and peripheral interfaces. Consider the active-low control requirement for compatibility with your microcontroller GPIOs. Evaluate the thermal performance given the 130 mOhm resistance if high ambient temperatures are expected. Compare against single-channel alternatives if only one rail requires switching to optimize board space.

Part Context

This device belongs to the MP6235x series of power switches from Monolithic Power Systems. It shares functional similarities with the MP62350 but offers dual channels instead of a single output. The series is characterized by low on-resistance and integrated protection features. It serves as a compact alternative to discrete MOSFET solutions for managing multiple power domains in space-constrained designs.

Replacement Considerations

The MP62350ES-LF-Z is a related single-channel variant within the same product family. Verify pin-to-pin compatibility and electrical parameter alignment before substitution. No other direct public substitutes are confirmed in the provided data.
