ADM709SARZ-REEL

Supervisors Overview

The ADM709SARZ-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor power supply integrity. It features a single monitored input with a threshold voltage of 2.93 V and an overvoltage threshold of 3 V. The device provides a push-pull output type and includes a reset delay time of 380 ms. It operates within a supply voltage range from 2.7 V to 5.5 V, with a typical operating supply current of 200 uA. The component supports surface mount installation in an SOIC-8 package and functions reliably across a temperature range of -40 C to +85 C.

Supervisors Feature Summary

• Provides continuous monitoring of a single voltage input channel for system supervision.
• Generates a reset signal using a push-pull output driver architecture.
• Includes specific timing characteristics such as a defined reset delay period.

Supervisors Applications

• Power supply monitoring in embedded systems
• Voltage supervision for microprocessor circuits
• System reset generation in industrial control units

Supervisors Procurement Notes

Verify the exact suffix designation when ordering, as the REEL variant indicates tape and reel packaging distinct from tube configurations. Confirm that the 2.93 V threshold aligns with the target application's voltage requirements. Ensure the SOIC-8 footprint matches the PCB layout constraints. Check for any regional distribution restrictions or discontinuation notices prior to finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 2.93 V threshold is required for low-voltage supervision applications. Consider the 200 uA operating current for power-sensitive designs. The push-pull output allows direct interfacing with digital logic without additional pull-up components. Evaluate the 380 ms reset delay against the system's startup timing requirements to ensure proper initialization sequences are maintained during power transitions.

Supervisors Part Context

This part belongs to the ADM709 series of supervisory circuits from Analog Devices. It serves as a specialized voltage monitor within the PMIC category. The device complements other variants in the family that offer different thresholds or packaging options. It is engineered for reliable operation in environments requiring precise voltage tracking and immediate reset assertion upon fault detection.
