DS1831CS

Supervisors Overview

The DS1831CS is a supervisory circuit designed for monitoring multiple power supplies. It features two independent voltage monitor channels with fixed thresholds of 3.3V and 5V. The device provides an active-low, open-drain reset output with a typical delay of 1.6 seconds. It supports manual reset functionality and includes power-fail detection capabilities. Operating within a supply range up to 5.5V, it maintains accuracy within 2.5% across the industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Dual-channel voltage monitoring with fixed 3.3V and 5V thresholds
• Active-low open-drain reset output with configurable manual reset input
• Integrated power-fail detection for reliable system supervision

Supervisors Applications

• Multi-supply embedded systems requiring simultaneous voltage supervision
• Industrial control units operating in harsh thermal environments
• Communication equipment needing stable power management

Supervisors Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Request official datasheets and material compliance documentation prior to purchase. Confirm package integrity and marking consistency against standard specifications. Ensure storage conditions meet manufacturer guidelines to prevent degradation. Validate supplier credentials to avoid counterfeit components.

Supervisors Selection Notes

Select this component when fixed threshold monitoring for 3.3V and 5V rails is required without adjustable settings. Consider the open-drain output compatibility with host logic levels. Evaluate the manual reset feature necessity for system recovery protocols. Assess the 2.5% accuracy requirement against system tolerance limits. Verify SOIC-16 package suitability for PCB layout constraints.

Supervisors Part Context

The DS1831C series belongs to Maxim Integrated's Micromonitor family, focusing on compact power supervision solutions. This specific part number represents the commercial grade variant housed in a surface-mount SOIC-16 package. It complements other devices in the lineup by offering dual-channel oversight in a minimal footprint, suitable for space-constrained designs.

Supervisors Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Cross-reference pinout and electrical characteristics before integrating any substitute. Ensure replacement parts maintain identical threshold voltages and output configurations.
