MPQ5073GG-Z

Overview

The MPQ5073GG-Z is an industrial-grade power switch IC from Monolithic Power Systems, designed for power distribution applications. It features a single output capable of handling up to 2A with a maximum on-resistance of 70 mOhms. The device operates within a supply voltage range of 3V to 5.5V and includes programmable current limiting set at 1.4A. It provides comprehensive protection against over-temperature conditions and under-voltage lockout. The component is housed in a compact QFN-12 package suitable for surface mount installation.

Feature Summary

• Industrial grade reliability for demanding environments
• Programmable current limit for flexible load management
• Low on-resistance for efficient power delivery
• Integrated thermal and under-voltage protection

Applications

• Industrial power distribution systems
• Load switching in automated control equipment
• Power management in industrial IoT devices

Procurement Notes

Verify the specific suffix GG-Z corresponds to the required QFN-12 package and tape-and-reel configuration. Confirm that the industrial temperature rating aligns with your system's operational requirements. Ensure compatibility with the 5.5V maximum supply voltage and 2A continuous current limits during design validation.

Selection Notes

Select this component when industrial durability and precise current limiting are required. Compare against standard grade alternatives if cost sensitivity outweighs environmental robustness needs. Consider the 70 mOhm on-resistance impact on thermal performance relative to the QFN-12 package size and expected ambient temperatures.

Part Context

This part belongs to the MPQ5073 series of load switches. It shares functional similarities with other MPS power distribution ICs but is distinguished by its industrial qualification and specific electrical parameters. The series offers various options for different current ratings and package types.
