DS1834DS

Supervisors Overview

The DS1834DS+ is a dual-channel voltage supervisor from the EconoReset series, designed for systems with dual power supplies. It monitors two inputs (typically 3.3V and 5V) and asserts active-low open-drain reset signals when voltages drop below thresholds of 2.97V or 4.75V. The device features a manual reset input via pushbutton, a 350ms reset delay, and operates within a supply range up to 5.5V. It draws 50uA current, maintains 2.5% accuracy, and functions between -40°C and +85°C in an SOIC-8 package.

Supervisors Feature Summary

• Dual channel monitoring for independent tracking of separate power rails
• Manual reset capability through integrated pushbutton interface
• Active low open drain output configuration for flexible logic interfacing

Supervisors Applications

• Systems requiring supervision of dual power supply architectures
• Embedded electronics needing manual system reset functionality
• Industrial control units operating across extended temperature ranges

Supervisors Procurement Notes

Verify component authenticity due to discontinued status. Confirm RoHS compliance details as documentation may vary by production batch. Check datasheet revisions for specific electrical characteristics before integration. Ensure sourcing channels provide valid traceability records for quality assurance purposes.

Supervisors Selection Notes

Select this component for applications requiring simultaneous monitoring of two distinct voltage levels without watchdog timer complexity. The manual reset feature distinguishes it from standard power-on reset only devices. Verify that the open-drain output type aligns with the target system's pull-up requirements and logic level compatibility.

Supervisors Part Context

Part of the Maxim Integrated EconoReset family, the DS1834DS+ serves as a legacy supervisory solution. It complements single-channel variants like the DS1833 and other dual-input models within the broader portfolio. This specific part number represents the industrial grade version in surface mount packaging.

Supervisors Replacement Considerations

Public confirmed substitute part numbers: DS1834AS+, DS1834S+. These variants share identical functional specifications but differ in package types such as T&R tape/reel options or alternative housing styles.
