DS1816R-5-U+W

Supervisors Overview

The DS1816R-5-U+W is a single-channel voltage supervisor IC from the EconoReset series by Analog Devices Inc./Maxim Integrated. It provides a reset signal with an active-low output in open-drain or open-collector configuration. The device monitors one input channel with a threshold voltage of 3.06V and ensures a minimum reset timeout of 100ms. It operates within a temperature range of -40°C to +85°C and is housed in a SOT-23-3 surface-mount package.

Supervisors Feature Summary

• Provides reliable power-on reset and system monitoring for single-supply applications
• Features an active-low open-drain or open-collector output compatible with various logic families
• Ensures system stability through a guaranteed minimum reset timeout period

Supervisors Applications

• Microprocessor and microcontroller power supply supervision
• Portable battery-powered equipment requiring low standby current
• Industrial control systems operating in wide temperature environments

Supervisors Procurement Notes

Verify the specific suffix 'U+W' against the manufacturer's latest datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure compatibility with the target PCB footprint, specifically the SOT-23-3 package dimensions. Confirm RoHS compliance status if required by your manufacturing standards.

Supervisors Selection Notes

Select this component when a simple, cost-effective solution for single-voltage monitoring is needed. The open-drain output allows for wired-OR configurations. Consider the 3.06V threshold relative to your system's nominal voltage to ensure proper reset triggering during brown-out conditions.

Supervisors Part Context

This part belongs to the DS1816 family of supervisory circuits. It is functionally similar to other EconoReset devices but distinguished by its specific threshold voltage and packaging. It serves as a fundamental building block for ensuring deterministic reset behavior in embedded systems.

Supervisors Replacement Considerations

Check for direct pin-to-pin replacements within the DS1816 series with different threshold voltages. Verify that any substitute maintains the same SOT-23-3 package and open-drain output type to avoid schematic modifications.
