DS1233Z-15/T&R

Supervisors Overview

The DS1233Z-15/T&R is a voltage supervisory circuit from the EconoReset series, manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single input voltage with a threshold of 4.125 V and an overvoltage threshold of 4.24 V. The device operates within a supply voltage range up to 5.5 V and features active low, open drain, or push-pull outputs. It includes power failure detection but lacks manual reset, watchdog timer, or battery backup switching capabilities. The reset delay time is specified at 350 ms, with an accuracy of 15%. Operating temperatures range from -40°C to +85°C, and it consumes 50 uA of working current.

Supervisors Feature Summary

• Provides power failure detection for system protection
• Offers flexible output configurations including active low, open drain, and push-pull
• Features low quiescent current consumption for energy efficiency

Supervisors Applications

• Embedded systems requiring voltage supervision
• Microcontroller reset circuits
• Industrial control equipment monitoring

Supervisors Procurement Notes

Verify the specific suffix T&R indicates tape and reel packaging when ordering. Confirm the exact part number matches the required threshold voltage and package type. Check manufacturer documentation for any recent product change notices or lifecycle status updates. Ensure compatibility with existing board designs regarding pinout and electrical specifications.

Supervisors Selection Notes

Select this component for applications needing simple voltage supervision without complex features like watchdogs or manual resets. Consider the 15% accuracy and 350 ms reset delay for timing requirements. Evaluate the SOT-223-3 package suitability for surface mount assembly processes. Compare against other EconoReset variants if different thresholds or accuracies are needed.

Supervisors Part Context

This part belongs to the DS1233 family of voltage supervisors. It is designed as a cost-effective solution for basic power management tasks.
