ADM709SAR

Supervisors Overview

The ADM709SAR is a voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.7 V to 5.5 V and features a reset threshold voltage of 2.93 V. The device provides a push-pull output with a reset delay time of 380 ms. It consumes 200 uA of operating current and detects overvoltage at a 3 V threshold. The component supports a maximum power dissipation of 470 mW and functions in temperatures from -40°C to +85°C. It is housed in an SOIC-8 package.

Supervisors Feature Summary

• Provides voltage supervision with a fixed 2.93 V threshold for monitoring single input lines
• Delivers active low, push-pull reset signals with a guaranteed 380 ms delay
• Operates across industrial temperature ranges without requiring manual reset or watchdog timers

Supervisors Applications

• Processor reset generation in embedded systems
• Power supply monitoring for microcontrollers
• Voltage supervision in industrial control circuits

Supervisors Procurement Notes

Verify the specific suffix against official documentation, as variations exist between tube and reel packaging formats. Confirm availability status, as some variants may be subject to end-of-life notices or limited distribution. Ensure the selected part number matches the required package type and thermal specifications for your design.

Supervisors Selection Notes

Select this component when a fixed 2.93 V threshold is required for system supervision. Consider the 380 ms reset delay for timing-sensitive applications. Verify that the SOIC-8 package fits the board layout constraints. Check if the 200 uA quiescent current meets power budget requirements compared to lower-power alternatives.

Supervisors Part Context

This part belongs to the ADM709 series of simple reset supervisors. It is designed for basic power management tasks where complex features like watchdogs are unnecessary. The series offers various threshold voltages and package options to suit different voltage rails and form factors.
