DS1816R-5+T&R

Supervisors Overview

The DS1816R-5+T&R is a single-channel voltage supervisor from the EconoReset series by Analog Devices Inc./Maxim Integrated. It provides power supply monitoring with a fixed threshold of 3.06V and an open-drain or open-collector output type. The device features a minimum reset timeout of 100ms and operates within a temperature range of -40°C to +85°C. Packaged in a surface-mount SOT-23-3 (TO-236-3, SC-59) case, it supports active-low reset signals for simple supervisory applications.

Supervisors Feature Summary

• Provides simple reset and power-on reset functionality for monitored circuits
• Features an open-drain or open-collector output interface
• Includes a manual reset input capability for system control

Supervisors Applications

• Embedded systems requiring power supply supervision
• Microcontroller-based designs needing reliable reset generation
• Portable electronics utilizing low-voltage operation

Supervisors Procurement Notes

Verify the specific suffix and tape/reel configuration when ordering to ensure compatibility with automated assembly processes. Confirm that the 3.06V threshold aligns with the target system's voltage requirements. Check for RoHS compliance status and lead times through authorized distributors. Ensure the SOT-23-3 package footprint matches the PCB design specifications before finalizing procurement.

Supervisors Selection Notes

Select this component for applications requiring a fixed 3.06V threshold with minimal external components. The open-drain output allows for flexible logic level interfacing. Consider the manual reset feature if user intervention is required during system initialization. Evaluate the operating temperature range against environmental conditions. Compare against other EconoReset variants if different thresholds or packages are needed.

Supervisors Part Context

This part belongs to the DS1816 family of voltage supervisors, designed for cost-sensitive applications. It complements other Maxim Integrated PMIC solutions by offering basic but reliable power management functions. The SOT-23-3 package ensures space efficiency for compact electronic devices.
