ADM2914-2ARQZ

Supervisors Overview

The ADM2914-2ARQZ is a quad voltage supervisor from Analog Devices, designed to monitor positive and negative supply rails. It features ±0.8% accuracy for under-voltage and over-voltage detection. The device provides open-drain reset outputs with adjustable delay times. It operates within a specified voltage range and supports surface-mount QSOP-16 packaging. This component ensures system reliability by detecting power anomalies in multi-rail environments.

Supervisors Feature Summary

• Monitors four independent voltage channels simultaneously
• Detects both under-voltage and over-voltage conditions
• Provides accurate threshold detection with low drift
• Generates reset signals upon fault detection

Supervisors Applications

• Multi-rail server power systems
• Industrial control equipment monitoring
• Telecommunications infrastructure power supplies
• Medical equipment power integrity verification

Supervisors Procurement Notes

Verify the exact suffix ARQZ matches the required package and temperature grade. Confirm availability status as distribution may vary. Ensure compatibility with existing board layout constraints for the QSOP-16 footprint. Check for any specific ordering restrictions or lifecycle notices before finalizing procurement plans.

Supervisors Selection Notes

Select this part when precise monitoring of multiple positive and negative rails is required. Consider the ±0.8% accuracy specification for critical applications. Evaluate the need for adjustable reset delays against system startup requirements. Compare pinout compatibility if replacing legacy components like the ADM2914.

Supervisors Part Context

This component belongs to the ADM12914/ADM2914 family of precision voltage supervisors. It serves as a robust solution for complex power management architectures requiring simultaneous oversight of multiple supply lines. The design focuses on high accuracy and reliable fault detection for sensitive electronic systems.

Supervisors Replacement Considerations

The ADM12914-2ARQZ is a direct functional replacement for the ADM2914-2ARQZ. Verify that the pinout and electrical characteristics remain identical during substitution. Ensure the new part number reflects the updated product designation while maintaining performance parity.
