DS1233M-55+T&R

Supervisors Overview

The DS1233M-55+T&R is a voltage supervisory circuit manufactured by Analog Devices under the Maxim Integrated brand. It operates within a supply voltage range of 1.2 V to 5.5 V and features a threshold voltage of 4.625 V with an overvoltage threshold of 4.75 V. The device provides power-fail detection and utilizes an active low, open drain output type. It includes a reset delay time of 350 ms and maintains an accuracy of 2.5%. The component functions without manual reset or watchdog timer capabilities and draws a working supply current of 50 uA. It is housed in a TO-92-3 package designed for through-hole mounting.

Supervisors Feature Summary

• Provides single-input voltage supervision with dedicated power-fail detection capability
• Features an active low open drain output interface for system integration
• Includes internal reset delay mechanism to ensure stable power-up sequences

Supervisors Applications

• Embedded systems requiring reliable power monitoring
• Microcontroller-based designs needing voltage supervision
• Industrial control units with strict power integrity requirements

Supervisors Procurement Notes

Verify component authenticity through authorized distribution channels due to limited availability status. Confirm that the specific suffix corresponds to the reel packaging format required for automated assembly processes. Ensure compatibility with existing board layouts regarding the through-hole pin configuration. Cross-reference datasheet specifications against current design requirements to validate electrical performance margins. Check regional shipping restrictions before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a through-hole voltage supervisor with open drain output is required. The 4.625 V threshold suits standard 5 V logic systems. Consider the 350 ms reset delay for timing-sensitive applications. Verify that the 50 uA quiescent current meets low-power design constraints. Ensure the TO-92-3 package fits the mechanical constraints of the target enclosure.

Supervisors Part Context

This part belongs to the DS1233M series of EconoReset circuits. It shares functional similarities with other variants in the family but differs in package style and specific threshold tolerances. The M-series designation indicates specific manufacturing characteristics distinct from surface-mount alternatives. It serves as a fundamental power management element in legacy and robust industrial designs.

Supervisors Replacement Considerations

Direct substitutes include DS1233MS-55+ for surface-mount equivalents. Other family members like DS1233-5+ offer similar functionality with different package options. Verify pinout compatibility and electrical parameter alignment before substitution.
