ADM709MAR-REEL

Supervisors Overview

The ADM709MAR-REEL is a supervisory circuit manufactured by Analog Devices Inc., designed to monitor a single voltage input. It features an active-low, push-pull output driver and operates within a supply voltage range of 1 V to 5.5 V. The device provides a minimum reset timeout of 140 ms and maintains functionality down to 1 V. It is available in an 8-SOIC surface-mount package with a width of 3.90 mm. The component supports industrial operating temperatures from -40°C to +85°C and complies with RoHS3 standards.

Supervisors Feature Summary

• Monitors a single power supply rail for under-voltage conditions
• Provides a guaranteed reset signal when supply voltage drops below the threshold
• Features an active-low, push-pull output compatible with TTL and CMOS logic

Supervisors Applications

• Microprocessor system supervision
• Portable equipment power management
• Controller board voltage monitoring

Supervisors Procurement Notes

Verify the specific suffix against official documentation to confirm reel packaging and exact threshold voltage variants. Ensure the ordering code matches the required reset delay and output configuration. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability and compliance status before procurement.

Supervisors Selection Notes

Select this component when a simple, low-cost supervisor is needed for single-rail monitoring. Consider the 140 ms minimum reset delay and 1 V operating limit during design. Verify that the 8-SOIC package fits the PCB layout constraints. Confirm compatibility with the target system's logic levels due to the push-pull output structure.
