DS1834A+

Supervisors Overview

The DS1834A+ is a dual voltage supervisor from the MicroMonitor family, designed to monitor two independent power rails. It features fixed thresholds 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. It operates within a supply voltage range up to 5.5 V and consumes 50 uA. The reset delay time is 350 ms, and it supports overvoltage detection at 2.97 V and 4.75 V respectively.

Supervisors Feature Summary

• Dual-channel monitoring for simultaneous supervision of separate power supplies
• Manual reset capability via dedicated pushbutton input
• Overvoltage detection functionality integrated into the supervisory circuit

Supervisors Applications

• Embedded systems requiring dual power rail supervision
• Industrial control units with mixed voltage logic levels
• Communication equipment needing reliable power failure detection

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm package type matches design requirements as variants exist. Check RoHS compliance documentation for specific manufacturing dates. Ensure supply chain stability given potential discontinuation risks associated with legacy Maxim Integrated products.

Supervisors Selection Notes

Select this component when dual voltage monitoring with manual override is required. Compare against single-channel alternatives if only one rail needs supervision. Consider thermal performance within the specified operating temperature range. Verify interface compatibility with target microcontroller reset pins.

Supervisors Part Context

Part of the MicroMonitor series focusing on simple, cost-effective power management solutions. Manufactured by Analog Devices Inc./Maxim Integrated, known for precision analog circuits. The DS1834A+ represents a specific variant in the broader DS1834 family, distinguished by its dual-channel configuration and fixed threshold settings.

Supervisors Replacement Considerations

DS1834AU+ and DS1834DS+ are confirmed substitutes within the same product family offering identical electrical characteristics.
