DS1831

Supervisors Overview

The DS1831 is a MicroMonitor power supply management circuit featuring four independent monitoring channels. It operates within a voltage range of 1V to 5.5V and supports multiple output configurations, including open-drain or open-collector reset signals with active-low polarity. The device provides configurable timeout delays ranging from 10ms to 1000ms minimum. It accommodates fixed thresholds at 3.3V and 5V alongside adjustable voltage trip levels. Designed for surface-mount installation in 16-pin PDIP and SOIC packages, it functions reliably across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates four independent voltage supervision channels within a single compact package
• Supports flexible threshold selection with both fixed standard voltages and programmable adjustable settings
• Provides configurable reset timeout delays to accommodate varying system startup requirements
• Delivers active-low reset outputs utilizing open-drain or open-collector topology

Supervisors Applications

• Multi-rail power supply systems requiring simultaneous voltage supervision
• Embedded controllers needing reliable brown-out protection
• Industrial equipment demanding robust fault detection during power transitions
• Communication infrastructure ensuring stable operation under variable input conditions

Supervisors Procurement Notes

Verify the specific suffix designation to confirm the exact package type and pinout configuration required for your design. Ensure that the selected variant matches the necessary thermal performance specifications for your operating environment. Cross-reference the datasheet to validate the supported voltage ranges and delay options against your system's power architecture before finalizing component selection.

Supervisors Selection Notes

Evaluate the available threshold options to determine if fixed or adjustable voltage trip points best suit your application needs. Consider the required reset timeout duration to ensure proper system initialization sequences are maintained. Assess the package constraints to select between through-hole or surface-mount formats based on board layout limitations. Confirm compatibility with the target operating temperature range for long-term reliability.
