DS1831C+

Supervisors Overview

The DS1831C+ is a MicroMonitor multi-supply voltage supervisor featuring four monitored channels in a 16-pin PDIP package. It provides open-drain or open-collector active-low reset outputs with configurable timeout delays of 10ms, 100ms, and 1,000ms minimum. The device supports threshold voltages of 2.5V and 3.3V alongside adjustable settings. Operating within a temperature range of -40°C to +85°C, it ensures reliable system supervision for multiple power rails.

Supervisors Feature Summary

• Monitors up to four independent supply voltages simultaneously
• Provides active-low reset signals via open-drain or open-collector outputs
• Features selectable reset timeout delays for flexible timing control

Supervisors Applications

• Multi-rail embedded system power supervision
• CPU and memory voltage monitoring
• Industrial control board power integrity checks

Supervisors Procurement Notes

Verify component authenticity through authorized distribution channels due to end-of-life status. Confirm RoHS compliance requirements as the standard DS1831C may not meet current environmental standards. Request detailed datasheets to validate pinout compatibility and electrical specifications against existing designs before procurement.

Supervisors Selection Notes

Select this component when designing systems requiring simultaneous monitoring of multiple voltage rails with precise reset timing. Ensure the required threshold voltages align with available fixed options or adjustability needs. Consider the through-hole packaging constraints and verify that the open-drain output interface matches the downstream logic input requirements.

Supervisors Part Context

Part of the Maxim Integrated MicroMonitor family designed for comprehensive power management supervision. This series addresses complex multi-supply environments by consolidating monitoring functions into a single integrated circuit solution.

Supervisors Replacement Considerations

The DS1831C is listed as End-of-Life. Verify availability of direct functional equivalents or updated revisions from Analog Devices that maintain identical pinouts and electrical characteristics for seamless integration.
