DS1233-5

Supervisors Overview

The DS1233-5 is a voltage supervisory circuit from the EconoReset series manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single input with a threshold voltage of 4.625 V and an overvoltage threshold of 4.75 V. The device supports a maximum supply voltage of 5.5 V and operates within a temperature range of -40°C to +85°C. It features a reset delay time of 350 ms, an accuracy of 5%, and a quiescent current of 50 uA. Available in TO-92-3 packages for through-hole mounting, it provides active low, open drain, or push-pull outputs without manual reset or watchdog timer capabilities.

Supervisors Feature Summary

• Provides power-fail detection for system supervision
• Offers flexible output configurations including active low, open drain, and push-pull modes
• Ensures stable operation across industrial temperature ranges

Supervisors Applications

• Embedded systems requiring voltage monitoring
• Microprocessor reset circuits
• Industrial control equipment

Supervisors Procurement Notes

Verify the specific package variant (TO-92-3) and suffix requirements against official datasheets before ordering. Confirm availability status as distribution channels may list discontinued or region-restricted stock. Ensure compatibility with existing board layouts regarding through-hole mounting constraints and pinout definitions.

Supervisors Selection Notes

Select this component when a simple, low-cost supervisor for 5V systems is required. Consider the 5% accuracy and 350 ms delay for timing-sensitive applications. Evaluate the absence of manual reset and watchdog features against system design needs. Compare alternative packages if surface-mount solutions are preferred over through-hole options.

Supervisors Part Context

Part of the DS1233 EconoReset family designed for basic voltage supervision tasks. This model specifically targets 5V logic systems with defined threshold levels. It serves as a fundamental building block for ensuring reliable power-up sequences in digital electronics without complex configuration requirements.

Supervisors Replacement Considerations

Check for direct substitutes within the DS1233 series such as DS1233Z-5+ for surface mount variants. Verify equivalent threshold voltages and output types when considering cross-manufacturer alternatives.
