DS1834A

Supervisors Overview

The DS1834A is a dual-channel voltage supervisor from the Maxim Integrated EconoReset family, designed for monitoring two independent power rails. It features fixed threshold voltages of 3.3 V and 5 V with an accuracy of 2.5%. The device provides active low open-drain outputs and includes a manual reset input. Key electrical parameters include a maximum supply voltage of 5.5 V, a reset delay time of 350 ms, and a quiescent current of 50 uA. It operates within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Dual-channel supervision for simultaneous monitoring of separate voltage rails
• Integrated manual reset capability via dedicated pushbutton input
• Open-drain output structure compatible with various logic families
• Low power consumption suitable for battery-operated systems

Supervisors Applications

• Embedded systems requiring dual power rail supervision
• Industrial control units with multiple voltage domains
• Consumer electronics utilizing standard 3.3V and 5V logic levels
• Automotive infotainment systems needing reliable power monitoring

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm RoHS compliance details and specific package variants (uMAX-8 or SOIC-8) against design requirements. Check for obsolescence notices or lifecycle changes as supply constraints may affect long-term procurement strategies.

Supervisors Selection Notes

Select this component when dual independent voltage monitoring is required without watchdog timer functionality. Ensure the fixed 3.3 V and 5 V thresholds align with target system rails. Consider the manual reset feature if hardware pushbutton integration is preferred over software-controlled resets. Verify package compatibility with existing PCB footprint constraints.

Supervisors Part Context

Part of the Maxim Integrated EconoReset series focusing on cost-effective supervisory solutions. Designed for applications requiring basic power management without complex configuration. Competes in the general-purpose voltage monitor segment where fixed thresholds and manual reset are sufficient.

Supervisors Replacement Considerations

DS1834AU+ and DS1834DS+ are verified pin-compatible alternatives offering identical electrical specifications with different package options.
