MP62040DQFU-1-LF-Z

Overview

The MP62040DQFU-1-LF-Z is a single-channel power distribution switch manufactured by Monolithic Power Systems. It operates within an input voltage range of 1.7V to 5.5V and supports a continuous output current of 2A. The device features integrated current limiting for circuit protection. A key functional distinction of the '-1' suffix variant is the inclusion of an active output discharge mechanism, which facilitates rapid load discharge when the switch is disabled. This component is housed in an ultra-small DQFU package.

Feature Summary

• Integrates active output discharge capability for rapid load voltage decay upon shutdown
• Provides single-channel power switching with built-in current limiting protection
• Operates across a wide supply voltage range from 1.7V to 5.5V

Applications

• Portable electronic devices requiring compact power management solutions
• Peripheral interface circuits needing controlled power distribution
• Systems utilizing low-voltage logic levels for power switching control

Procurement Notes

Verify the specific suffix 'DQFU-1' to confirm the presence of the output discharge feature, as standard variants lack this function. Ensure the ordering part number matches the exact package type and thermal requirements. Cross-reference the manufacturer's latest datasheet to confirm RoHS compliance status and any recent design revisions before finalizing procurement specifications.

Selection Notes

Select this component when a small footprint is critical and rapid load discharge is required after shutdown. Compare against standard MP62040 variants if output discharge is unnecessary, as those may offer different cost or availability profiles. Evaluate the 2A current limit against peak load demands to ensure adequate headroom without triggering false fault conditions during normal operation transients.

Part Context

This device belongs to the MP62040 family of ultra-small power distribution switches from Monolithic Power Systems. The family includes variants such as the MP62040 and MP62040-1, distinguished primarily by the presence or absence of the output discharge feature. These components are designed for applications demanding high integration and minimal board space utilization in low-voltage power routing scenarios.

Replacement Considerations

The MP62040DQFU-LF-Z serves as a direct substitute if the output discharge functionality is not required in the application. Verify pin compatibility and electrical parameters before swapping between these variants.
