DS1831DS+T&R

Supervisors Overview

The DS1831DS+T&R is a multi-supply voltage supervisor integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It features four monitored channels with fixed thresholds of 3.3V and 2.5V, packaged in a 16-SOIC surface-mount housing. The device provides open-drain or open-collector outputs with active-low reset signals. It supports configurable reset timeouts of 10ms, 100ms, and 1,000ms minimums. Operating within a temperature range of -40°C to +85°C, it is designed for reliable power system monitoring in industrial and commercial applications.

Supervisors Feature Summary

• Monitors multiple supply voltages simultaneously using fixed threshold levels
• Provides manual reset capability via dedicated input pin
• Offers configurable timeout delays for reset signal generation
• Features low-power operation suitable for battery-backed systems

Supervisors Applications

• Multi-rail power supply supervision in embedded systems
• Industrial control unit power integrity monitoring
• Telecommunications equipment voltage tracking
• Computer peripheral power management circuits

Supervisors Procurement Notes

Verify the exact suffix 'DS' against the manufacturer's current datasheet to confirm threshold specifications. Ensure the tape-and-reel packaging matches your automated assembly requirements. Cross-reference the RoHS compliance status with recent environmental declarations. Confirm availability through authorized distributors as stock levels fluctuate. Validate the operating temperature range meets your specific application constraints before finalizing procurement.

Supervisors Selection Notes

Select this component when fixed 3.3V and 2.5V monitoring thresholds are required without external resistor programming. Consider the 16-SOIC package size for PCB layout compatibility. Evaluate the manual reset feature necessity for system recovery protocols. Compare the configurable timeout options against system startup timing requirements. Assess the open-drain output interface compatibility with downstream logic levels.

Supervisors Part Context

This part belongs to the MicroMonitor series from Maxim Integrated, now part of Analog Devices. The series focuses on compact, low-power supervisory solutions for complex multi-voltage environments. The DS1831 variant specifically addresses applications requiring simultaneous monitoring of distinct voltage rails with minimal external component count.

Supervisors Replacement Considerations

Check for DS1831ES or DS1831BS variants if different threshold combinations are needed. Verify pinout compatibility before substituting with other 16-SOIC supervisors. Confirm that alternative parts support the same manual reset functionality and timeout configurations.
