DS1831S

Supervisors Overview

The DS1831S+ is a MicroMonitor voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It features four monitored inputs with open-drain or open-collector active-low reset outputs. The device supports threshold voltages of 3.3V, 5V, and adjustable levels. It operates within a supply voltage range of 1V to 5.5V and includes manual reset functionality. Reset timeout delays are configurable at 10ms, 100ms, or 1,000ms minimums. The component is housed in a 16-SOIC package and functions reliably across an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides multi-supply monitoring for up to four independent voltage rails
• Offers configurable reset time delays to accommodate specific system startup requirements
• Supports manual reset input for external control of the reset state

Supervisors Applications

• Multi-voltage power supply management systems
• Embedded systems requiring supervised power sequencing
• Industrial control units with multiple logic voltage domains

Supervisors Procurement Notes

Verify the exact suffix designation when ordering, as variations such as DS1831AS+ or DS1831BS+ may exist with different fixed threshold characteristics. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability for this specific part number can vary. Ensure the selected variant matches the required threshold configuration for your design.

Supervisors Selection Notes

Select the DS1831S+ when a supervisory circuit with four monitored channels and adjustable thresholds is required. Consider the 16-SOIC package constraints and the need for manual reset capability. Evaluate if the configurable delay options meet the system's power-up timing specifications compared to fixed-delay alternatives.

Supervisors Part Context

The DS1831 belongs to the Maxim Integrated MicroMonitor family of voltage supervisors. This series is designed for applications requiring reliable power management in environments with multiple voltage supplies. The S+ suffix typically denotes a specific package and commercial/industrial temperature grade variant within the broader product line.

Supervisors Replacement Considerations

DS1831BS+ is listed as a parameter-equivalent alternative within the same manufacturer portfolio.
