DS1233M-55

Supervisors Overview

The DS1233M-55 is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range up to 5.5 V and features a threshold voltage of 4.625 V with an accuracy of 2.5%. The device provides power failure detection and generates an active low, open drain reset output with a delay time of 350 ms. Designed for through-hole installation in TO-92-3 packages, it supports a single monitored input without manual reset or watchdog timer functions. Operating currents are specified at 50 uA, and the component withstands overvoltage thresholds of 4.75 V across temperatures from -40 C to +85 C.

Supervisors Feature Summary

Supervisors Procurement Notes

Verify the exact suffix designation when ordering, as variations such as tape-and-reel packaging may affect availability. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Ensure the specific package type matches your board layout requirements before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a simple voltage supervisor with power fail indication is required. Consider the fixed threshold voltage and lack of manual reset functionality during design. Evaluate the through-hole package constraints against available PCB space and mounting preferences.

Supervisors Part Context

This part belongs to the DS1233M series of EconoReset monitoring circuits. It serves as a fundamental building block for ensuring system stability by detecting abnormal voltage conditions. The series focuses on providing essential reset and power fail signaling without complex configuration options.

Supervisors Replacement Considerations

Consult official documentation for direct substitutes within the same family. Verify pin compatibility and electrical specifications before integrating alternative components into existing designs.
