DS1816R-10-U

Supervisors Overview

The DS1816R-10-U is a supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for monitoring single voltage inputs. It operates within a supply voltage range of 2.7 V to 5.5 V and features a threshold voltage of 3.0 V with 10% accuracy. The device provides a reset timeout of 140 ms minimum and supports active low or open drain output configurations. It is housed in a compact SOT-23-3 package, suitable for surface mount applications across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates power-fail detection and manual reset functionality for comprehensive system supervision
• Offers configurable output states including active low and open-drain options for flexible interface compatibility
• Provides precise voltage monitoring with specified threshold accuracy for reliable trigger points

Supervisors Applications

• Embedded systems requiring dedicated power management supervision
• Microcontroller-based designs needing reliable brown-out protection
• Industrial control units operating in variable thermal environments

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to discontinued status. Confirm RoHS compliance and specific suffix variations against official datasheets. Validate pinout compatibility during integration planning. Check for obsolescence notices from the manufacturer. Ensure storage conditions meet semiconductor handling standards.

Supervisors Selection Notes

Evaluate the required reset delay time against system startup requirements. Compare threshold voltage accuracy needs with available options. Consider package size constraints relative to PCB layout limitations. Assess output drive capabilities for downstream logic interfacing. Review temperature range specifications for environmental suitability.

Supervisors Part Context

This component belongs to the DS1816 series of micromonitor circuits, which are engineered for cost-effective power supervision. The series typically integrates watchdog timers and voltage monitoring into a single small-footprint package. These devices support various output configurations to accommodate different system architectures and logic levels.

Supervisors Replacement Considerations

Consult official cross-reference lists for verified substitutes. Verify pin-to-pin compatibility before implementation. Confirm electrical parameter alignment with original specifications.
