DS1831DS

Supervisors Overview

The DS1831DS+ is a MicroMonitor multi-supply supervisor circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors up to four system voltages, including fixed 5V and 3.3V inputs, plus two user-configurable channels. The device operates within a temperature range of -40°C to +85°C and utilizes a 16-SOIC surface-mount package. Reset timeout durations are configurable at 10ms, 100ms, or 1,000ms. Voltage thresholds include fixed 2.5V and 3.3V options alongside adjustable settings. The output type is open-drain or open-collector with active-low reset signaling.

Supervisors Feature Summary

• Monitors multiple power rails simultaneously for system stability
• Provides manual pushbutton reset override capability
• Includes watchdog timer functionality in specific variants
• Configurable reset time delays for transient handling

Supervisors Applications

• Multi-supply embedded systems requiring voltage supervision
• CPU supervisor circuits with power-fail warnings
• Industrial control systems operating in extended temperatures
• Automotive electronics monitoring critical power rails

Supervisors Procurement Notes

Verify component authenticity through authorized distributors as the part is obsolete. Check manufacturer notices for lifecycle status updates. Confirm RoHS compliance and REACH registration details before integration. Ensure supply chain continuity plans address end-of-life constraints. Validate datasheet revisions against current design requirements.

Supervisors Selection Notes

Evaluate compatibility with existing voltage rails against fixed threshold options. Consider thermal performance within the specified operating range. Assess pinout requirements for the 16-SOIC package layout. Review configuration options for reset delays and watchdog functions. Compare against newer supervisory ICs for long-term availability.

Supervisors Part Context

Part of the Maxim Integrated MicroMonitor family designed for multi-supply environments. Replaces earlier Dallas Semiconductor versions with updated manufacturing processes. Shares functional similarities with DS1831BS and DS1831ES variants. Designed for robust operation in industrial and automotive sectors. Integrates precision voltage references for accurate monitoring.

Supervisors Replacement Considerations

Public confirmed substitute part numbers: DS1831BS+, DS1831ES+. Verify pin compatibility and threshold specifications before substitution.
