DS1831DS+

Supervisors Overview

The DS1831DS+ is a MicroMonitor multi-supply voltage supervisor manufactured by Analog Devices Inc./Maxim Integrated. It monitors four independent voltage rails using fixed thresholds of 2.5V and 3.3V, alongside two adjustable inputs. The device features an active-low open-drain reset output with configurable timeout delays of 10ms, 100ms, or 1,000ms. Operating within a supply range up to 5.5V, it supports manual reset functionality and operates across a temperature range of -40°C to +85°C in a 16-SOIC package.

Supervisors Feature Summary

• Monitors multiple power supplies simultaneously with dedicated fixed and adjustable threshold channels
• Provides active-low open-drain reset signal with selectable timeout delay configurations
• Supports manual reset input for system control override capabilities

Supervisors Applications

• Multi-rail embedded system power supervision
• Industrial controller voltage monitoring
• Communication equipment power integrity management

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance and manufacturing origin via official documentation. Check for obsolescence notices and potential supply chain restrictions before finalizing procurement plans.

Supervisors Selection Notes

Select this component when simultaneous monitoring of four distinct voltage levels is required. Ensure the available fixed thresholds of 2.5V and 3.3V align with target rails. Verify that the adjustable inputs can accommodate remaining supply voltages within the specified operating range.

Supervisors Part Context

Part of the Maxim Integrated MicroMonitor family designed for comprehensive power system oversight. This specific variant integrates both fixed and programmable sensing capabilities into a single surface-mount package, simplifying board layout for complex multi-voltage architectures.

Supervisors Replacement Considerations
