ADM823ZYKSZ-R7

Supervisors Overview

The ADM823ZYKSZ-R7 is a single-channel power supply management circuit manufactured by Rochester Electronics, functioning as a voltage supervisory device. It operates within an extended temperature range of -40°C to +125°C and utilizes a 5-pin TSSOP package compliant with the MO-203AA/SC-70 standard. The component features a fixed reset threshold voltage of 2.32V and does not support adjustable thresholds. It is RoHS compliant and lead-free, designed for monitoring power systems in industrial or commercial applications requiring precise voltage supervision.

Supervisors Feature Summary

• Provides fixed voltage supervision with a specific reset threshold of 2.32V
• Operates reliably across an extended industrial temperature range from -40°C to +125°C
• Utilizes a compact 5-pin surface-mount package for space-constrained designs

Supervisors Applications

• Single-rail power supply monitoring in embedded systems
• Voltage supervision for microcontroller reset circuits
• Industrial control system power integrity verification

Supervisors Procurement Notes

Verify that the specified 2.32V reset threshold aligns with the target system's logic levels and brown-out requirements. Confirm compatibility with the 5-pin TSSOP footprint during PCB layout. Ensure the sourcing channel provides valid traceability documentation, as this part is distributed by Rochester Electronics rather than direct Analog Devices manufacturing lines.

Supervisors Selection Notes

Select this component when a fixed 2.32V supervision level is required without external resistor networks. Consider the SC-70/TSSOP-5 form factor for minimal board area consumption. Evaluate the -40°C to +125°C operating range against environmental conditions. Note that the threshold is non-adjustable, limiting flexibility compared to programmable supervisors.

Supervisors Part Context

This part belongs to the ADM823 series of supervisory circuits, which are designed for monitoring single power rails. Distributed by Rochester Electronics, it represents a specialized variant of the broader Analog Devices portfolio, focusing on cost-effective, fixed-threshold solutions for standard voltage monitoring tasks in general-purpose electronics.

Supervisors Replacement Considerations

Direct substitutes include other ADM823 variants with different fixed thresholds (e.g., ADM823SYKSZ-R7 for 2.63V, ADM823TYKSZ-R7 for 3.08V) if the 2.32V level is unsuitable. Verify pinout compatibility across all SC-70-5 packages before substitution.
