DS1831BS+

Supervisors Overview

The DS1831BS+ is a MicroMonitor™ 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 open-drain or open-collector outputs with active-low reset signals. Reset timeouts are configurable at minimum values of 10ms, 100ms, and 1,000ms. It operates within a supply voltage range of 1V to 5.5V and supports an operating temperature range of -40°C to +85°C. The component is housed in a 16-SOIC surface-mount package.

Supervisors Feature Summary

• Supports monitoring of up to four distinct power supply rails simultaneously
• Configurable reset timeout delays for system stability management
• Includes manual reset input capability for user-initiated control
• Provides open-drain/open-collector output interface compatibility

Supervisors Applications

• Multi-supply microprocessor systems requiring comprehensive power supervision
• Embedded controllers needing configurable voltage threshold monitoring
• Industrial equipment utilizing multiple regulated voltage domains
• Communication infrastructure managing complex power sequencing requirements

Supervisors Procurement Notes

Verify the specific suffix designation against official datasheets to confirm pinout and electrical characteristics match your design requirements. Ensure the selected variant aligns with your thermal management strategy and PCB layout constraints. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the manufacturer's latest documentation to validate any potential obsolescence notices or recommended design changes before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when designing systems that require simultaneous monitoring of multiple voltage rails including fixed and adjustable levels. Consider the available reset timeout options to ensure proper system initialization sequences. Evaluate the package size relative to your board space limitations. Verify that the open-drain output configuration matches your downstream logic requirements. Assess the operating temperature range against your environmental conditions.
