MPQ5074GQBE-AEC1-Z

Overview

The MPQ5074GQBE-AEC1-Z is a single-channel load switch IC from Monolithic Power Systems, designed for automotive power distribution. It supports an input voltage range of 1.2 V to 5.5 V and delivers a continuous output current of 3 A. The device features a low on-resistance of 13 mOhms maximum and includes configurable current limit options at 1.7 A or 3 A. Qualified under AEC-Q100 standards, it operates within a temperature range of -40°C to +125°C and is housed in a compact 13-PowerVQFN package.

Feature Summary

Configurable current limit functionality allows selection between fixed threshold values to protect downstream loads.
Low on-resistance design minimizes conduction losses and improves system efficiency during normal operation.
Integrated fault protection mechanisms include overcurrent limiting, short-circuit protection, and undervoltage lockout.

Applications

Automotive infotainment system power distribution
Sensor module power switching in vehicle networks
Peripheral device load switching in automotive ECUs

Procurement Notes

Verify the specific suffix against official MPS documentation to confirm exact current limit configuration and package variant. Ensure the component meets AEC-Q100 grade requirements for the target automotive application environment. Cross-reference the datasheet revision with the ordered part number to validate parameter consistency before integration.

Selection Notes

Select this component when a single-channel high-current load switch with configurable protection is required. Compare the 13 mOhm on-resistance against thermal constraints in the specific PCB layout. Evaluate the available current limit settings to ensure adequate margin for inrush currents without nuisance tripping during startup phases.

Part Context

This part belongs to the MPQ5074 series of automotive-grade load switches. It complements other MPS power management solutions by providing robust distribution capabilities. The series is characterized by its ability to handle significant current loads while maintaining low voltage drop across the switch channel.
