DS1834AU+

Supervisors Overview

The DS1834AU+ is a dual-channel 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 two monitored inputs with threshold voltages of 3.3 V and 5 V. The device provides an active low, open-drain output and includes manual reset functionality via a pushbutton input. It has a reset delay time of 350 ms and power-fail detection capabilities. Packaged in an 8-pin uMAX format, it supports surface mount installation and functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Dual-channel monitoring for independent voltage supervision
• Manual reset capability through dedicated pushbutton interface
• Power-fail detection for system integrity assurance

Supervisors Applications

• Embedded systems requiring dual power rail supervision
• Industrial control units needing manual reset interfaces
• Consumer electronics with strict power failure detection requirements

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to limited availability status. Confirm package type matches design requirements as variations exist within the series. Check RoHS compliance documentation for specific manufacturing batches. Ensure thermal management aligns with specified operating temperature ranges during integration.

Supervisors Selection Notes

Select this component when dual voltage monitoring with manual reset is required. Compare against similar models like DS1834DS+ for package differences. Consider current consumption specifications for battery-operated designs. Verify threshold voltage compatibility with target power rails before finalizing selection.

Supervisors Part Context

Part of the DS1834 series focusing on dual-channel supervision. Shares functional similarities with other EconoReset devices but differs in package configuration. Designed for compact applications where space efficiency is critical. Represents Maxim Integrated's approach to simplified power management solutions.

Supervisors Replacement Considerations

DS1834DS+ offers identical electrical characteristics in SOIC-8 packaging. DS1834S+ provides equivalent performance in standard SOIC-8 form factor. Verify pinout compatibility when substituting between uMAX and SOIC packages.
