ADM809TART-REEL

Supervisors Overview

The ADM809TART-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for microprocessor reset applications. It operates within a supply voltage range of 1 V to 5.5 V and features a push-pull output type. The device monitors a single input and provides a reset delay time of 240 ms. It is available in an SOT-23-3 package with surface mount installation style. The component functions without manual reset, watchdog timer, or battery backup switch capabilities. Operating temperatures range from -40 C to +125 C, with a typical quiescent current of 60 uA.

Supervisors Feature Summary

• Provides reliable voltage supervision for microprocessor systems
• Features push-pull output configuration for direct interface compatibility
• Operates across extended industrial temperature ranges

Supervisors Applications

• Microprocessor reset circuits
• Voltage monitoring in embedded systems
• Power management ICs

Supervisors Procurement Notes

Verify the specific revision status and RoHS compliance details directly with the manufacturer or authorized distributors, as availability may be restricted. Confirm that the SOT-23-3 package matches your PCB footprint requirements. Ensure the 240 ms reset delay aligns with your system's startup timing constraints before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a simple, low-current voltage supervisor is required for single-input monitoring. The 60 uA quiescent current makes it suitable for power-sensitive designs. Verify that the 5.5 V maximum operating voltage covers your system's peak supply levels. Consider the 240 ms reset delay to ensure adequate stabilization time for downstream logic components during power-up events.

Supervisors Part Context

This part belongs to the ADM809 series of supervisory circuits from Analog Devices. It serves as a dedicated reset generator for digital systems requiring precise voltage threshold monitoring. The series offers various threshold options to accommodate different logic families and supply rails, ensuring robust system reliability across diverse electronic applications.

Supervisors Replacement Considerations

Check for ADM809 variants with compatible packages and thresholds. Verify electrical parameters such as reset delay and quiescent current against existing design specifications to ensure functional equivalence.
