ADM8617SAYAKSZ-RL7

Supervisors Overview

The ADM8617SAYAKSZ-RL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single-input power rails. It integrates a watchdog timer to detect processor malfunctions and generate system resets. The device operates within a supply voltage range up to 5.5 V, with a threshold voltage of 2.93 V and an accuracy of 2.5%. It features an active low, open-drain output and a reset delay time of 1.4 ms. The component is housed in a SC-70-4 package, suitable for surface mount installation, and functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for automated system recovery from software faults
• Provides precise voltage supervision with factory-set threshold levels
• Features an active low open-drain reset output for flexible logic interfacing

Supervisors Applications

• Embedded systems requiring processor reset protection
• Portable electronic devices with limited power budgets
• Industrial control units needing reliable voltage monitoring

Supervisors Procurement Notes

Verify the specific suffix 'AKSZ' against the official datasheet to confirm the exact threshold voltage and package variant, as suffixes often denote specific electrical or mechanical configurations. Ensure the ordering part number matches the required reel quantity and tape-and-reel specifications for your assembly line. Cross-reference the manufacturer's latest documentation to confirm current production status and any potential obsolescence notices before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a single-supply voltage monitor with integrated watchdog functionality is required. It is appropriate for designs needing a compact SC-70-4 footprint and low quiescent current. Consider the 2.93 V threshold and 2.5% accuracy against your system's minimum operating voltage. Verify that the active low open-drain output aligns with your microcontroller's reset input requirements without additional pull-up components if not already present.
