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 housed in a 16-SOIC package. The device provides open-drain or open-collector outputs with active-low reset signals. Threshold voltages include fixed 3.3V and 5V options, alongside two adjustable thresholds. Reset timeout delays are selectable at minimums of 10ms, 100ms, and 1,000ms. Operating temperature ranges from -40°C to +85°C.

Supervisors Feature Summary

• Supports monitoring of up to four independent power supply rails simultaneously
• Provides configurable reset timeout delays for system stability
• Features open-drain or open-collector output structure for flexible interfacing

Supervisors Applications

• Multi-voltage embedded systems requiring simultaneous power supervision
• Industrial control units with mixed voltage logic levels
• Telecommunications equipment power management circuits

Supervisors Procurement Notes

Verify the specific suffix configuration against the manufacturer datasheet to ensure correct threshold and delay selections. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the 16-SOIC package dimensions match the target PCB footprint requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when multiple voltage rails require centralized supervision within a single IC. The adjustable thresholds allow customization for non-standard voltage levels. Verify that the required reset delay meets the system's startup timing constraints. Ensure the operating temperature range aligns with the intended environmental conditions.

Supervisors Part Context

This part belongs to the MicroMonitor series designed for power supply support applications. It integrates multiple supervisor functions into a compact surface-mount package. The series is engineered for reliability in industrial and commercial environments. It simplifies board design by reducing the component count associated with power monitoring.
