DS1818R-5/T&R

Supervisors Overview

The DS1818R-5/T&R is a single-channel power supply support circuit manufactured by Analog Devices Inc./Maxim Integrated. It functions as a supervisor with an open-drain or open-collector output and provides a low-active reset signal. The device features a minimum reset timeout of 100ms and operates within a temperature range of -40°C to +85°C. It is housed in a SOT-23-3 package and supports surface mount installation.

Supervisors Feature Summary

• Provides simple reset and power-on reset functionality for monitored voltage channels
• Features open-drain or open-collector output configuration
• Includes a minimum reset timeout duration of 100ms

Supervisors Applications

• Monitoring single-channel power supply voltages
• Implementing system reset circuits in embedded designs
• Power management supervision in industrial equipment

Supervisors Procurement Notes

Verify the specific suffix T&R indicates reel packaging when sourcing. Confirm the manufacturer designation matches Analog Devices Inc. or Maxim Integrated. Ensure the part number corresponds to the 5V threshold variant. Check current availability status as distribution may be limited.

Supervisors Selection Notes

Select this component for applications requiring a dedicated supervisor for a single voltage rail. The SOT-23-3 package suits space-constrained surface mount designs. Verify that the 100ms reset timeout meets system stability requirements before integration.

Supervisors Part Context

This part belongs to the EconoReset series, designed for basic power supply monitoring tasks. It serves as a cost-effective solution for systems needing reliable reset generation without complex programmability. The series focuses on essential supervisory functions in a compact form factor.

Supervisors Replacement Considerations

DS1818R-5-U+ is a confirmed substitute part number offering identical supervisory functions.
