ADM709RAN

Supervisors Overview

The ADM709RAN is a power supply monitor and reset generator integrated circuit manufactured by Analog Devices Inc. It provides system reset signals during power-up, power-down, and brownout conditions. The device features an active-low push-pull/totem-pole output and monitors a single voltage input with a threshold of 2.63 V. It operates within a temperature range of -40°C to +85°C and is housed in an 8-PDIP package.

Supervisors Feature Summary

• Generates system reset signals during power-up, power-down, and brownout events
• Features an active-low push-pull or totem-pole output driver
• Monitors a single voltage input channel for threshold detection

Supervisors Applications

• Microprocessor system reset generation
• Power supply monitoring in embedded systems
• Brownout protection circuits

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm the specific suffix 'RAN' corresponds to the 8-PDIP package and 2.63V threshold variant. Check for end-of-life status or obsolescence notices from Analog Devices prior to final procurement decisions.

Supervisors Selection Notes

Select this component when a fixed 2.63V threshold is required for low-voltage monitoring applications. The 8-PDIP package suits through-hole designs. Ensure the active-low output logic aligns with the target microcontroller or logic interface requirements. Verify that the 140ms minimum reset timeout meets system stability needs.

Supervisors Part Context

The ADM709 series belongs to Analog Devices' line of supervisory circuits designed for reliable power management. This specific model integrates voltage monitoring and reset generation into a single compact package, simplifying design complexity compared to discrete solutions. It is part of a broader family including variants with different thresholds and packages.

Supervisors Replacement Considerations

Publicly confirmed substitute part numbers are not explicitly listed in the provided source material for the ADM709RAN specifically. Cross-reference with other ADM709 variants or MAX709 series components only if electrical parameters match exactly.
