DS1831BS+T&R

Supervisors Overview

The DS1831BS+T&R is a multi-supply supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It features four monitored voltage channels with thresholds of 3.3V, 5V, and two adjustable inputs. The device provides active-low reset outputs via an open-drain or open-collector configuration. Reset timeout delays are selectable at minimum values of 10ms, 100ms, and 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 manual reset capability for system control
• Offers selectable reset delay times to accommodate various startup requirements

Supervisors Applications

• Multi-power-supply systems requiring simultaneous voltage supervision
• Embedded systems needing configurable reset timing sequences
• Industrial equipment operating in extended temperature environments

Supervisors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and electrical characteristics. Ensure the ordering information matches the required package type and thermal specifications. Cross-reference the component marking code with the datasheet to authenticate the source and prevent counterfeit components during acquisition.

Supervisors Selection Notes

Select this component when designing circuits that require supervision of both fixed and variable voltage rails. The adjustable threshold inputs allow customization for non-standard supply levels. Consider the open-drain output structure for interfacing with different logic voltage domains. Verify that the selected reset delay meets the system's power-up stability requirements.

Supervisors Part Context

This part belongs to the MicroMonitor series of supervisory circuits from Maxim Integrated. It is designed for applications requiring robust power management without complex external components. The series supports various monitoring configurations to simplify board design in multi-rail systems.
