MPQ6400DG-01-AEC1-LF-Z

Supervisors Overview

The MPQ6400DG-01-AEC1-LF-Z is a voltage supervisory circuit designed for automotive applications. It features a single monitored input with an open-drain output and manual reset capability. The device operates within a supply voltage range of 1.8 V to 6 V, drawing a quiescent current of 1.85 uA. It provides a threshold voltage of 400 mV and a reset delay time of 380 ms. Accuracy is specified at 1%. The component is housed in a QFN-6 package and supports operation from -40°C to +85°C.

Supervisors Feature Summary

• Designed specifically for automotive power management environments
• Provides low quiescent current consumption for energy efficiency
• Features programmable delay for precise reset timing control

Supervisors Applications

• Automotive electronic control unit (ECU) monitoring
• Power-on reset supervision in vehicle systems
• Voltage monitoring for AEC-Q100 compliant modules

Supervisors Procurement Notes

Verify the specific suffix 'AEC1' confirms automotive qualification status. Ensure the QFN-6 package matches the target PCB footprint. Confirm RoHS compliance documentation is available for regulatory requirements. Cross-reference the manufacturer part number against official distributor catalogs to avoid counterfeit components.

Supervisors Selection Notes

Select this supervisor when automotive reliability is required alongside low power consumption. The fixed 400 mV threshold suits specific low-voltage monitoring needs. Consider the manual reset feature if external user intervention is necessary for system recovery. Evaluate the QFN-6 package constraints for thermal and spatial limitations in dense automotive assemblies.

Supervisors Part Context

This component belongs to the MPQ series of Monolithic Power Systems, which targets high-reliability automotive markets. It complements other supervisors in the MP6400 family by offering AEC-Q100 certification. The device addresses the need for robust voltage monitoring in harsh automotive electrical environments.

Supervisors Replacement Considerations

Direct substitutes include MPQ6400DG-01-LF-Z for non-automotive grades or MP6400DJ-33-LF-Z for different threshold specifications. Verify package compatibility and functional equivalence before substitution.
