DS1233MS-55

Supervisors Overview

The DS1233MS-55 is a voltage supervisory circuit from the EconoReset series, designed for monitoring single-input power rails. It features a threshold voltage of 4.625 V and an overvoltage threshold of 4.75 V. The device operates within a supply voltage range up to 5.5 V and maintains a typical quiescent current of 50 uA. It provides a reset delay time of 350 ms with an accuracy of 2.5%. The output is active low, open drain, and push-pull. Packaged in SOIC-8 surface mount format, it supports operation across a temperature range of -40 C to +85 C.

Supervisors Feature Summary

• Provides power-fail detection and voltage supervision for single-channel applications
• Features manual reset capability alongside automatic power-on reset functions
• Includes battery backup switch functionality to maintain system integrity during power transitions

Supervisors Applications

• Embedded systems requiring reliable voltage supervision
• Microcontroller-based designs needing power-fail signaling
• Industrial control units operating in varying thermal environments

Supervisors Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm package type and electrical characteristics. Ensure compatibility with required threshold voltages and output configurations before integration. Cross-reference datasheet specifications for thermal performance and supply current limits to validate suitability for the target application environment.

Supervisors Selection Notes

Select this component when a surface-mount solution with precise voltage monitoring is required. Consider the SOIC-8 package for space-constrained PCB layouts. Evaluate the 2.5% accuracy and 350 ms reset delay against system timing requirements. Confirm that the active low output aligns with the downstream logic interface needs.

Supervisors Part Context

This part belongs to the DS1233 family of supervisory circuits, offering integrated reset generation and power management features. It complements through-hole variants like the DS1233M by providing a compact surface-mount alternative. The series is characterized by low power consumption and robust performance across industrial temperature ranges.

Supervisors Replacement Considerations

Direct substitutes include other members of the DS1233MS series with matching threshold voltages, such as the DS1233MS-5 or DS1233MS-10. Verify pinout compatibility and output drive strength when transitioning between different threshold variants within the same package.
