DS1831S+T&R

Supervisors Overview

The DS1831S+T&R is a multi-supply voltage supervisor integrated circuit from the MicroMonitor series, manufactured by Analog Devices Inc./Maxim Integrated. It features four monitored voltage inputs with thresholds of 3.3V, 5V, and two adjustable channels. The device provides active-low reset outputs in an open-drain or open-collector configuration. Reset timeout delays are selectable at minimum values of 10ms, 100ms, or 1,000ms. It operates within a temperature range of -40°C to 85°C and is housed in a 16-SOIC surface-mount package.

Supervisors Feature Summary

• Monitors multiple power supply rails simultaneously for system integrity
• Provides configurable reset timing delays to ensure stable startup
• Features adjustable voltage thresholds for flexible design integration

Supervisors Applications

• Multi-voltage embedded systems requiring supervisory control
• Industrial equipment with complex power distribution networks
• Telecommunications infrastructure monitoring critical voltage levels

Supervisors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact threshold configurations and delay options. Ensure the component matches the required operating temperature range and package specifications for your application. Cross-reference datasheet parameters with your system requirements before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when designing systems that require simultaneous monitoring of four distinct voltage rails. Consider the adjustable threshold capabilities if standard fixed voltages do not meet specific circuit requirements. Evaluate the available reset timeout options to align with your system's startup sequence and stability needs.
