ADM809-5SART-REEL

Supervisors Overview

The ADM809-5SART-REEL is a microprocessor supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single voltage inputs. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 5 V. The device provides a push-pull output with an 840 ms reset delay time, ensuring stable system initialization. It lacks manual reset, watchdog timer, and battery backup switch functionalities. The component is housed in an SC-70-3 package, suitable for surface mount installation, and functions reliably across a temperature range of -40°C to +125°C with a typical operating current of 60 uA.

Supervisors Feature Summary

• Provides dedicated voltage supervision for single-input power rails
• Delivers a deterministic reset signal via push-pull output architecture
• Operates effectively in extended industrial temperature environments

Supervisors Applications

• Microprocessor power supply monitoring
• Embedded system voltage supervision
• Industrial control unit reset generation

Supervisors Procurement Notes

Verify the exact suffix configuration against official Analog Devices documentation, as variations such as SARTZ or RAKS may indicate different tolerance levels or packaging formats. Confirm RoHS compliance status directly from the manufacturer's datasheet, as availability and regulatory markings can vary by production batch. Ensure the specific reel quantity matches project requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed 5 V threshold is required for systems operating near that rail. The SC-70-3 package offers space efficiency for compact designs. Consider the 840 ms delay duration to ensure it aligns with the target processor's startup timing requirements. Verify that the absence of a watchdog timer does not conflict with safety-critical application needs.

Supervisors Part Context

This part belongs to the ADM809 series of voltage supervisors from Analog Devices. The series includes variants with different threshold voltages (e.g., 2.5 V, 3 V, 3.3 V) and packages. The ADM809-5 specifically targets 5 V logic systems. The 'SART' designation typically indicates a specific tape-and-reel packaging format for automated assembly processes.
