DS1233-15+

Supervisors Overview

The DS1233-15+ is a voltage supervisory circuit from the EconoReset series by Analog Devices Inc./Maxim Integrated. It monitors a single input voltage with a threshold of 4.625 V and an overvoltage threshold of 4.75 V. The device features a reset delay time of 350 ms and operates within a supply voltage range up to 5.5 V. It provides active low, open drain, or push-pull output types. The component includes power-fail detection but lacks manual reset, watchdog timer, or battery backup switch functions. It is available in SOT-223-4 packages for surface mount applications.

Supervisors Feature Summary

• Provides power-fail detection for monitoring system voltage integrity
• Offers flexible output configurations including active low, open drain, and push-pull modes
• Features a fixed reset delay time to ensure stable power-up sequencing

Supervisors Applications

• Embedded systems requiring simple voltage supervision
• Microprocessor reset circuits
• Portable electronic devices with limited power budgets

Supervisors Procurement Notes

Verify the exact suffix designation (e.g., Z vs A) as it indicates specific package types and manufacturing revisions. Confirm RoHS compliance status through official manufacturer documentation. Ensure the sourcing channel provides valid traceability for Analog Devices components. Check for any regional distribution restrictions that may affect availability.

Supervisors Selection Notes

Select this component when a fixed threshold supervisor is sufficient for the application. Consider the SOT-223-4 package if space constraints require a compact surface-mount solution. Evaluate the 350 ms reset delay against system startup requirements. Verify that the 5% accuracy meets the design margin needs for the monitored rail.

Supervisors Part Context

This part belongs to the DS1233 family of voltage supervisors designed for cost-sensitive applications. The EconoReset line focuses on providing essential monitoring functions without complex features like watchdog timers or adjustable thresholds. It serves as a basic protection mechanism for digital logic and microcontrollers against brown-out conditions.

Supervisors Replacement Considerations

Direct substitutes include other DS1233 variants with compatible thresholds and packages. Cross-reference with DS1233Z-5+ for similar functionality in different voltage ranges. Verify pin compatibility before substitution.
