ADM709TAR-REEL

Supervisors Overview

The ADM709TAR-REEL is a supervisory circuit manufactured by Analog Devices Inc., designed to monitor a single voltage input. It operates within a supply voltage range of 1 V to 5.5 V and features a threshold voltage of 4.75 V, with a minimum monitored voltage of 4.65 V. The device provides a low-active push-pull output and includes a reset delay time of up to 380 ms. It is housed in an 8-pin SOIC package and supports surface mount installation. The component functions across a temperature range of -40 °C to +85 °C.

Supervisors Feature Summary

• Monitors a single power supply rail for under-voltage conditions
• Provides a low-active push-pull reset signal upon fault detection
• Includes a fixed reset delay timer to ensure stable power-up sequencing

Supervisors Applications

• Processor and microcontroller power supply supervision
• Battery-powered system voltage monitoring
• General-purpose voltage supervisor in embedded electronics

Supervisors Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration distinct from tube variants. Confirm the exact threshold voltage matches design requirements as the base part number may cover multiple voltage options. Check current availability status as distribution channels may list limited stock or end-of-life notices for reel-specific quantities.

Supervisors Selection Notes

Select this variant when automated surface-mount assembly requires reel packaging rather than tubes. Ensure the 4.75 V threshold aligns with the target system voltage. Verify that the 380 ms reset delay meets the timing constraints of the controlled logic. Confirm compatibility with the 8-SOIC footprint and operating temperature range.

Supervisors Part Context

This component belongs to the ADM709 series of simple reset generators and voltage supervisors from Analog Devices. It serves as a dedicated power management IC for ensuring reliable system startup and operation by detecting abnormal supply voltages. The series is commonly used in industrial and consumer applications requiring robust power integrity.
