ADM8617RCYAKSZ-RL7

Supervisors Overview

The ADM8617RCYAKSZ-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 system software failures and ensure reliable operation. The device operates within a supply voltage range of 1 V to 5.5 V, with specific under-voltage and over-voltage thresholds set at 2.55 V and 2.7 V respectively, while the standard threshold is 2.63 V. It features open-drain and push-pull output configurations without manual reset or battery backup switching capabilities. The component consumes 20 µA of operating current and functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for automated system recovery from software faults
• Provides dual output drive options including open-drain and push-pull configurations
• Monitors a single input voltage rail with dedicated under-voltage and over-voltage detection

Supervisors Applications

• Embedded systems requiring watchdog supervision
• Portable devices with low-power voltage monitoring needs
• Industrial control circuits operating in wide temperature environments

Supervisors Procurement Notes

Verify component authenticity through official Analog Devices channels due to End-of-Life status. Confirm package integrity for SC-70-4 SMD/SMT mounting. Check RoHS compliance documentation as specified in manufacturer records. Ensure design-in compatibility with existing 1 V to 5.5 V supply architectures before procurement.

Supervisors Selection Notes

Select this component when single-rail supervision with integrated watchdog functionality is required. Consider the 20 µA quiescent current for battery-sensitive designs. Verify that the 2.55 V/2.7 V threshold settings align with target system voltage levels. The SC-70-4 package suits space-constrained PCB layouts.
