DS1831CS+T&R

Supervisors Overview

The DS1831CS+T&R is a MicroMonitor multi-supply supervisor integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It features four independent monitoring channels housed in a 16-SOIC surface-mount package. The device provides open-drain or open-collector outputs with active-low reset signals. It supports fixed voltage thresholds of 3.3V and 5V, alongside two adjustable threshold inputs. Reset timeout delays are configurable to minimum values of 10ms, 100ms, or 1,000ms. The component operates within a temperature range of -40°C to 85°C.

Supervisors Feature Summary

• Provides simultaneous supervision for multiple power rails using four distinct monitoring channels
• Allows flexible configuration of voltage trip levels through fixed 3.3V and 5V options combined with adjustable inputs
• Offers programmable reset delay times to accommodate various system startup requirements

Supervisors Applications

• Multi-rail power supply management systems
• Embedded systems requiring comprehensive voltage supervision
• Industrial control units with complex power architectures

Supervisors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and electrical specifications. Ensure the ordering information matches the required package type and thermal characteristics. Cross-reference the part number with authorized distributors to validate authenticity and current availability status before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when designing systems that require independent monitoring of multiple voltage domains. Consider the adjustable threshold capabilities if standard fixed voltages do not align with specific rail requirements. Evaluate the available reset timeout options to ensure proper sequencing during power-up events. Confirm that the SOIC package dimensions fit the target PCB layout constraints.

Supervisors Part Context

This device belongs to the MicroMonitor family of supervisory circuits designed for robust power management. It serves as a critical safety component in electronic systems by detecting abnormal voltage conditions. The integration of multiple channels into a single package reduces board space compared to discrete solutions. It complements other Maxim Integrated analog and mixed-signal products used in industrial and consumer applications.

Supervisors Replacement Considerations

Consult official substitution guides for compatible alternatives within the same product family. Verify that any replacement maintains identical channel counts and output logic types.
