ADM824SYRJZ-REEL7

Supervisors Overview

The ADM824SYRJZ-REEL7 is a supervisory circuit manufactured by Analog Devices Inc., housed in a SOT-23-5 surface-mount package. It functions as a voltage supervisor with an integrated watchdog timer and features a push-pull output type. The device operates within a supply voltage range of up to 5.5 V and monitors a single input. Key electrical specifications include a threshold voltage of 2.93 V, an overvoltage threshold of 2.96 V, and a reset delay time of 280 ms. It draws a working power current of 24 uA and supports an operating temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system monitoring alongside voltage supervision capabilities.
• Features a push-pull output configuration for direct interface with digital logic.
• Designed for high-temperature operation suitable for industrial environments.

Supervisors Applications

• Microprocessor system reset circuits
• Watchdog timer implementations in embedded systems
• Voltage supervision in portable electronic devices

Supervisors Procurement Notes

Verify the specific suffix 'SYRJZ' against the official Analog Devices datasheet to confirm pinout and thermal characteristics. Ensure the SOT-23-5 footprint matches your PCB layout requirements. Confirm that the 2.93 V threshold aligns with your system's brown-out detection needs. Check for any RoHS compliance documentation if required by your manufacturing standards.

Supervisors Selection Notes

Select this component when a combined voltage supervisor and watchdog function is required in a minimal footprint. The SOT-23-5 package offers space efficiency compared to larger packages. Consider the 24 uA quiescent current for battery-powered applications. Verify that the 280 ms reset delay meets your system's startup timing constraints.

Supervisors Part Context

This part belongs to the ADM824 series of supervisory circuits from Analog Devices. It is designed to provide reliable system management by monitoring power rails and ensuring processor integrity through watchdog functionality. The series is commonly used in applications requiring robust fault detection and recovery mechanisms.

Supervisors Replacement Considerations

Consult the official Analog Devices replacement guide or datasheet for confirmed substitute part numbers. Do not assume compatibility based on similar package types alone. Verify electrical parameters such as threshold voltage and reset delay before substitution.
