ADM2914-2ARQZ-RL7

Supervisors Overview

The ADM2914-2ARQZ-RL7 is a quad voltage supervisor from Analog Devices, designed to monitor four independent input channels for under-voltage and over-voltage conditions. It features adjustable threshold voltages and reset delay times, allowing customization for specific system requirements. The device provides open-drain outputs and operates within a supply voltage range up to 6.8 V. Packaged in a 16-pin QSOP, it supports negative voltage monitoring capabilities alongside positive rails, ensuring comprehensive power integrity management for complex electronic systems.

Supervisors Feature Summary

• Monitors four independent voltage inputs for under-voltage and over-voltage events
• Features adjustable threshold voltages and reset delay times for flexible configuration
• Provides open-drain output signals for interface compatibility with various logic families
• Supports monitoring of both positive and negative voltage rails

Supervisors Applications

• Multi-rail power supply monitoring in industrial equipment
• System protection in telecommunications infrastructure
• Voltage supervision in automotive electronic control units
• Power management in embedded computing systems

Supervisors Procurement Notes

Verify the exact suffix -RL7 indicates reel packaging when sourcing. Confirm availability status as distribution channels may report limited stock or end-of-life notices. Ensure the QSOP-16 package matches your PCB footprint requirements. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm pinout and electrical specifications before finalizing procurement orders.

Supervisors Selection Notes

Select this component when simultaneous monitoring of four distinct voltage rails is required. The adjustable thresholds allow adaptation to varying rail tolerances without external resistor networks. Consider the open-drain output type for level shifting needs. Evaluate the operating temperature range against environmental conditions. Verify that the 16-pin QSOP package fits the available board space constraints.

Supervisors Part Context

This part belongs to the ADM2914 series of quad supervisors. It shares functional similarities with other ADI voltage monitors but offers specific quad-channel integration. The -2A variant typically denotes specific threshold or performance characteristics defined by the manufacturer. It serves as a dedicated solution for multi-supply systems requiring robust fault detection and reset generation.

Supervisors Replacement Considerations

Check for ADM2914 variants with different suffixes for package or temperature differences. Compare ADM3201 or ADM3202 for dual-channel alternatives if fewer monitors are needed. Verify pin-to-pin compatibility with existing designs before substituting. Consult Analog Devices for current lifecycle status and recommended alternative components.
