ADM709TARZ-REEL

Supervisors Overview

The ADM709TARZ-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor a single power supply rail. It operates within a supply voltage range of 1 V to 5.5 V and features a fixed threshold voltage of 4.65 V, with a maximum monitored voltage of 4.75 V. The device provides an active-low, push-pull reset output with a typical reset delay time of 380 ms. It is housed in an 8-pin SOIC package and supports surface-mount installation. The component functions reliably across an industrial temperature range from -40 °C to +85 °C.

Supervisors Feature Summary

• Provides automatic system reset when the monitored supply voltage drops below the specified threshold level
• Features an active-low, push-pull output driver for direct interface with digital logic circuits
• Includes internal timing mechanisms to ensure stable reset assertion during power-up sequences

Supervisors Applications

• Microprocessor and microcontroller power supply monitoring
• Battery-powered equipment voltage supervision
• Industrial control system power integrity verification

Supervisors Procurement Notes

Verify the specific suffix configuration against current manufacturer documentation to confirm pinout and electrical characteristics. Confirm availability status as distribution channels may list limited stock or end-of-life conditions. Ensure the reel packaging format matches automated assembly requirements. Cross-reference the exact part number with official datasheets to validate operating temperature ranges and package dimensions before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed 4.65 V threshold is required for systems powered between 1 V and 5.5 V. The 380 ms reset delay suits applications tolerant of standard power-up transients. The SOIC-8 package offers a compact footprint for space-constrained designs. Consider alternative threshold voltages if the target supply rail differs significantly from the 4.65 V specification.

Supervisors Part Context

This part belongs to the ADM709 series of simple reset generators and voltage supervisors from Analog Devices. The series typically includes variants with different threshold voltages and reset delays to accommodate various standard logic families and power rails. The TARZ suffix indicates a specific thermal and packaging configuration within the broader ADM709 product line.
