DS1834AS+

Supervisors Overview

The DS1834AS+ is a dual-channel voltage supervisor from the MicroMonitor series by Analog Devices Inc./Maxim Integrated. It monitors two power rails with fixed thresholds of 3.3 V and 5 V, featuring an active-low open-drain reset output. The device includes manual reset capability via a pushbutton input and provides a 350 ms reset delay. It operates within a supply voltage range up to 5.5 V, maintains 2.5% accuracy, and functions across a temperature range of -40°C to +85°C in an SOIC-8 package.

Supervisors Feature Summary

• Dual-channel monitoring for independent power rail supervision
• Manual reset functionality through dedicated pushbutton input
• Active-low open-drain reset signal generation
• Fixed threshold configuration for standard voltage levels

Supervisors Applications

• Embedded systems requiring dual power supply supervision
• Industrial control units with mixed voltage architectures
• Consumer electronics utilizing 3.3V and 5V logic domains

Supervisors Procurement Notes

Verify component authenticity due to discontinued status. Confirm RoHS compliance documentation matches specific manufacturing lot requirements. Validate package integrity against SOIC-8 specifications. Ensure thermal performance aligns with operational limits. Cross-reference datasheet revisions for any functional updates.

Supervisors Selection Notes

Evaluate compatibility with system voltage profiles against fixed 3.3 V and 5 V thresholds. Assess manual reset integration needs versus automatic supervision. Consider operating temperature range constraints for environmental deployment. Review current consumption requirements against system power budgets. Verify package footprint compatibility with existing PCB layouts.

Supervisors Part Context

Part of the Maxim Integrated MicroMonitor family designed for reliable power management. Offers simplified supervision for multi-rail systems without complex programming. Provides robust protection against brown-out conditions in compact surface-mount packaging.

Supervisors Replacement Considerations

DS1834S+ serves as a direct pin-compatible alternative within the same series. Verify identical threshold voltages and package dimensions before substitution.
