ADM2914-1ARQZ-RL7

Supervisors Overview

The ADM2914-1ARQZ-RL7 is a quad voltage supervisory integrated circuit designed for monitoring multiple power rails. It features four independent channels, each capable of detecting both under-voltage and over-voltage conditions for positive and negative supplies. The device utilizes an open-drain output configuration and operates within a maximum supply voltage of 6.8 V. Key adjustable parameters include the threshold voltage and reset delay time. It is housed in a 16-pin QSOP package and supports surface mount installation.

Supervisors Feature Summary

• Quad channel architecture for simultaneous monitoring of multiple power rails
• Capable of detecting both under-voltage and over-voltage events on positive and negative supplies
• Adjustable threshold voltage and reset delay time settings
• Open-drain output interface for flexible logic integration

Supervisors Applications

• Monitoring multiple power rails in complex electronic systems

Supervisors Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm that the received part matches the specific ordering suffix -RL7, which indicates tape and reel packaging. Ensure storage and handling procedures comply with moisture sensitivity levels to maintain reliability before assembly.

Supervisors Selection Notes

Select this component when a single IC solution is required to monitor four distinct voltage rails simultaneously. It is suitable for designs needing independent adjustment of trip points and reset delays for each channel. Consider the open-drain output compatibility with system logic levels and the QSOP package constraints during PCB layout planning.
