MPQ5074GQBE-AEC1-P

Overview

The MPQ5074GQBE-AEC1-P is a single-channel automotive-grade load switch designed for power distribution applications. 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, with maximum values of 13 mOhms and 16 mOhms depending on the configuration. It includes a configurable current limit settable at 1.7 A or 3 A. Operating within a temperature range of -40°C to +125°C, it utilizes a QFN-13 package.

Feature Summary

Configurable current limit allows selection between 1.7 A and 3 A thresholds
Low on-resistance minimizes power loss in high-current paths
AEC-Q100 qualification ensures reliability for automotive environments

Applications

Automotive power distribution units
Peripheral power switching in vehicle electronics
High-side load protection circuits

Procurement Notes

Verify that the specific suffix matches the required current limit setting, as the part number indicates a configurable option. Confirm the QFN-13 package dimensions align with the PCB footprint. Ensure the supply voltage range covers the system's minimum operating requirements. Check RoHS compliance status for environmental regulations. Validate thermal performance under maximum load conditions.

Selection Notes

Choose this component when a single channel with adjustable overcurrent protection is required. The low on-resistance makes it suitable for efficient power delivery. Consider the 1.2 V start-up capability for systems with varying rail voltages. The wide operating temperature range supports harsh automotive environments. Evaluate the trade-off between the two current limit options based on load characteristics.

Part Context

This device belongs to the MPQ5074 series of load switches from Monolithic Power Systems. It is part of a family of automotive-grade power management ICs designed for robust operation. The series offers various configurations for different current and voltage requirements. It complements other MPS solutions for complete power distribution architectures.
