ADM709MARZ

Supervisors Overview

The ADM709MARZ is a single-channel voltage supervisor IC manufactured by Analog Devices Inc., designed for simple reset and power-on reset applications. It features an active-low, push-pull output driver housed in an 8-SOIC surface-mount package with a width of 3.90mm. The device monitors a single input voltage with a threshold of 4.4V and supports a maximum operating supply voltage of 5.5V, starting from a minimum of 1V. It ensures system reliability with a minimum reset timeout of 140ms and operates within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides active-low reset signal generation via push-pull output driver
• Monitors single voltage channel with fixed threshold detection
• Supports surface-mount installation in compact 8-lead SOIC packaging

Supervisors Applications

• Microprocessor and microcontroller system supervision
• Power-on reset circuitry for digital logic systems
• Battery-powered device voltage monitoring

Supervisors Procurement Notes

Verify the specific suffix 'MARZ' corresponds to the 8-SOIC package and commercial temperature grade during procurement. Confirm RoHS compliance status as indicated in official documentation. Check for any product change notices or end-of-life announcements prior to finalizing design-in decisions to ensure long-term availability.

Supervisors Selection Notes

Select this component when a fixed 4.4V threshold is required for single-supply monitoring. Ensure the application does not require manual reset inputs or watchdog timer functionality, as these are absent in this variant. Verify that the 140ms minimum timeout meets the target processor's initialization requirements.

Supervisors Part Context

This part belongs to the ADM709 series of supervisory circuits. It is functionally related to other variants in the family that may offer different thresholds, packages, or additional features like manual reset pins. The 'M' indicates the SOIC package, while 'ARZ' denotes the temperature range and lead-free status.

Supervisors Replacement Considerations

MAX709MCSA+ is listed as a similar alternative. Verify pin compatibility and threshold voltage differences before substitution.
