DS1233DZ-15/T&R

Supervisors Overview

The DS1233DZ-15+T&R is a single-channel voltage supervisor from the EconoReset series, manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.2V to 3.3V and features a fixed threshold voltage of 4.125V for power monitoring. The device provides an active-low reset output with a minimum timeout period of 250ms. Designed for surface-mount assembly, it utilizes a SOT-223-3 package (TO-261-4/TO-261AA). The component supports open-drain or open-collector outputs and functions reliably across an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides automatic system reset upon detection of under-voltage conditions
• Features a fixed threshold voltage for simplified design integration
• Includes a guaranteed minimum reset timeout period to ensure stable power-up sequences

Supervisors Applications

• Microprocessor and microcontroller power supply supervision
• Battery-powered electronic systems requiring low-voltage monitoring
• Portable devices needing reliable power-fail detection

Supervisors Procurement Notes

Verify the exact suffix against official manufacturer documentation to confirm package type and tape-and-reel specifications. Confirm that the ordering part number matches the required threshold voltage and output configuration. Ensure compatibility with the target PCB footprint, specifically the SOT-223-3 variant. Cross-reference the datasheet for any specific handling or storage requirements relevant to this component revision.

Supervisors Selection Notes

Select this component when a fixed 4.125V threshold is appropriate for the monitored rail. Consider the SOT-223-3 package constraints for thermal management and board space. Evaluate the 250ms minimum reset timeout against the system's power-up stability requirements. Verify that the active-low open-drain/open-collector output interface aligns with the downstream logic input requirements.

Supervisors Part Context

This part belongs to the DS1233A/D EconoReset family of supervisory circuits. These components are designed for cost-sensitive applications requiring basic voltage monitoring without complex programmability. The series typically offers various threshold options and package configurations to accommodate different system architectures and form factors.

Supervisors Replacement Considerations

Consult official substitution guides for equivalent parts with matching threshold voltages and package dimensions. Verify functional compatibility regarding reset timeout characteristics and output drive capabilities before implementation.
