DS1831BS

Supervisors Overview

The DS1831BS+ is a MicroMonitor multi-supply supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It provides four independent voltage monitoring channels within a 16-SOIC surface-mount package. The device supports fixed thresholds of 3.3V and 5V, alongside two adjustable threshold inputs. It features an active-low reset output with open-drain or open-collector configuration. The component operates across a temperature range of -40°C to +85°C and includes programmable reset timeout delays of 10ms, 100ms, and 1,000ms.

Supervisors Feature Summary

• Monitors multiple power supply rails simultaneously for system integrity
• Configurable reset timeout durations for flexible startup sequencing
• Supports both fixed and user-defined voltage trip levels

Supervisors Applications

• Multi-voltage embedded system supervision
• Industrial control board power management
• Telecommunications equipment reset logic

Supervisors Procurement Notes

Verify the specific suffix designation when ordering, as variations exist between standard and tape-and-reel packaging options. Confirm that the selected variant matches the required pinout and thermal characteristics for the target application environment. Cross-reference the manufacturer part number against official distributor catalogs to ensure authenticity and traceability before finalizing procurement.

Supervisors Selection Notes

Select this component when designing systems requiring simultaneous oversight of distinct voltage domains. Ensure the available adjustable input pins align with the specific voltage requirements of the application. Verify that the open-drain reset output compatibility matches the downstream logic interface. Consider the operating temperature range constraints relative to the intended deployment environment.

Supervisors Part Context

This device belongs to the MicroMonitor family of supervisory circuits designed for complex power architectures. It addresses the need for reliable reset generation in environments where multiple voltage rails must be validated concurrently. The integration of adjustable thresholds allows for customization without changing the core silicon design.
