ADM6823SYRJZ-RL7

Supervisors Overview

The ADM6823SYRJZ-RL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., featuring an integrated watchdog timer and manual reset capability. It operates within a supply voltage range up to 5.5 V and monitors a single input channel. The device provides an active low, push-pull output with a fixed reset delay time of 200 ms. Key electrical parameters include a threshold voltage of 2.93 V, an overvoltage threshold of 3 V, and an accuracy of 2.5%. It consumes 20 uA of operating current and lacks battery backup switching or power failure detection features.

Supervisors Feature Summary

• Integrates a watchdog timer function for system monitoring alongside voltage supervision capabilities.
• Includes a manual reset input allowing for direct user-initiated system resets.
• Delivers an active low, push-pull output signal for interfacing with digital logic.

Supervisors Applications

• Embedded systems requiring voltage supervision and watchdog protection
• Microcontroller-based designs needing manual reset functionality
• Industrial control circuits operating within specified temperature ranges

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity as the device is in SOT-23-5 format. Check datasheet revisions for any parameter updates. Ensure compatibility with existing board layouts given the specific threshold voltage. Validate supply chain sources against manufacturer recommendations for obsolete parts.

Supervisors Selection Notes

Choose this part when a 2.93 V threshold is required for single-input monitoring. Consider the 20 uA quiescent current for low-power applications. Verify that the 200 ms reset delay meets timing requirements. Ensure the SOT-23-5 package fits the design constraints. Confirm that manual reset and watchdog features align with system architecture needs.

Supervisors Part Context

This component belongs to the ADM6823 series of supervisory circuits from Analog Devices.
