ADM825SYRJZ-R7

Supervisors Overview

The ADM825SYRJZ-R7 is a supervisory circuit manufactured by Analog Devices Inc., designed to monitor power supply voltage levels and ensure system integrity. It features a manual reset capability and operates within a supply voltage range of 3.5 V to 5.5 V. The device provides a threshold voltage of 3.08 V with an accuracy of 2.5%. It includes a reset delay time of 280 ms and draws a typical operating supply current of 24 uA. Packaged in a SOT-23-5 format, it supports surface mount installation and functions across a temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Monitors power supply voltage levels for system supervision
• Includes manual reset functionality for controlled recovery
• Operates with low quiescent current consumption
• Provides push-pull output for direct interface compatibility

Supervisors Applications

• Microprocessor supervisory circuits
• Battery-powered systems requiring voltage monitoring
• Industrial control systems needing reliable reset mechanisms
• Portable electronic devices with limited power budgets

Supervisors Procurement Notes

Verify the specific suffix 'R7' indicates reel packaging when ordering. Confirm the 'S' variant corresponds to the specified threshold and package type against the official datasheet. Ensure the manual reset feature aligns with system design requirements. Check for any regional distribution restrictions or limited availability status prior to finalizing procurement plans.

Supervisors Selection Notes

Select this component when a supervisory circuit with manual reset is required for voltage monitoring applications. Consider the 2.5% accuracy and 280 ms delay for timing-sensitive designs. Evaluate the 24 uA supply current against battery life constraints. Ensure the SOT-23-5 package fits the PCB layout constraints and thermal requirements of the target environment.

Supervisors Part Context

This part belongs to the ADM82x series of supervisory circuits from Analog Devices, which are designed for monitoring power supplies and code execution integrity. The series typically includes variants with different thresholds and reset capabilities. The ADM825 specifically focuses on voltage supervision with manual reset options, distinguishing it from watchdog-only or auto-reset variants within the broader family.

Supervisors Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit designs if considering alternative supervisory ICs from other manufacturers.
