ADM709TAN

Supervisors Overview

The ADM709TAN is a single-channel power supply monitor and reset generator IC manufactured by Analog Devices Inc. It provides system reset signals during power-up, power-down, and brownout conditions. The device features a fixed threshold voltage of 3.08V with a minimum reset timeout of 140ms. It operates within a supply voltage range of 3V to 5V and supports an industrial temperature range from -40°C to +85°C. The component utilizes an 8-pin Plastic DIP (N-8) package and delivers a push-pull/totem pole output.

Supervisors Feature Summary

• Generates reliable system reset signals during power-up, power-down, and brownout events
• Features a fixed voltage monitoring threshold for precise supervision
• Provides active low push-pull or totem pole output drive capability

Supervisors Applications

• Microprocessor system supervision
• Digital circuit power management
• Brownout detection in embedded systems

Supervisors Procurement Notes

Verify the specific suffix 'TAN' corresponds to the 8-pin Plastic DIP (N-8) package variant when sourcing. Confirm the fixed 3.08V threshold aligns with design requirements. Check current lifecycle status as older ADM709 variants may be subject to discontinuation notices. Ensure compatibility with existing PCB footprints for through-hole mounting.

Supervisors Selection Notes

Select this part for applications requiring a fixed 3.08V reset threshold without manual reset inputs. The 8-pin DIP package suits prototyping or legacy through-hole designs. Compare against SOIC variants if surface mount space is constrained. Verify that the 140ms minimum timeout meets system startup timing requirements.

Supervisors Part Context

The ADM709 series belongs to Analog Devices' portfolio of simple reset supervisors. These components are designed to replace discrete resistor-capacitor networks for reset generation. The T-series typically denotes specific package and temperature grade combinations within the broader ADM709 family.
