DS1233Z-10

Supervisors Overview

The DS1233Z-10 is a voltage supervisory circuit from the EconoReset series, designed to monitor power supply integrity. It features a single monitored input with a threshold voltage of 3.3 V and an active low open-drain output. The device includes manual reset functionality and provides a reset delay time of 450 ms. It operates within a supply voltage range of 1.2 V to 5.5 V and supports surface mount installation in an SOT-223-3 package. The component functions across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides automatic power-fail detection for system protection
• Includes manual reset capability for user-initiated control
• Features active low open-drain output interface

Supervisors Applications

• Microprocessor system supervision
• Power management monitoring
• Embedded controller reset generation

Supervisors Procurement Notes

Verify current availability status as distribution channels may indicate limited stock or discontinuation. Confirm RoHS compliance requirements against specific project standards. Ensure the SOT-223-3 package footprint matches the target PCB design. Validate that the 3.3 V threshold aligns with the monitored rail specifications before finalizing procurement.

Supervisors Selection Notes

Select this component when a simple, low-cost supervisory solution is required for single-rail monitoring. The absence of a watchdog timer simplifies design if software-based timing is preferred. Verify that the 450 ms reset delay meets the system startup timing requirements. Consider the manual reset pin requirement if external push-button integration is feasible within the enclosure design.

Supervisors Part Context

This part belongs to the DS1233A/Z EconoReset family, which offers basic voltage supervision without complex features like battery backup switches or chip enable signals. It serves as a fundamental building block for ensuring reliable operation in digital systems by detecting under-voltage conditions and initiating resets.

Supervisors Replacement Considerations

Check for direct substitutes within the DS1233 series such as DS1233AZ-10/TR/C16 for identical electrical characteristics but different packaging. Verify pinout compatibility when considering alternative packages like TO-92-3 variants.
