DS1818R-10+T&R

Supervisors Overview

The DS1818R-10+T&R is a single-channel voltage supervisor from the EconoReset series, manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 2.88 V. The device provides a low-active reset signal with a minimum timeout of 100 ms via an open-drain or open-collector output. Designed for surface-mount applications, it is housed in a SOT-23-3 package and supports operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides simple reset and power-on reset functionality for monitored circuits
• Features manual pushbutton reset capability for system control
• Detects power failures to ensure reliable system state management

Supervisors Applications

• Portable equipment requiring low standby current
• Battery-powered systems needing power-fail detection
• Microprocessor and microcontroller supervisory circuits

Supervisors Procurement Notes

Verify the specific suffix 'R-10' confirms the 2.88 V threshold and SOT-23-3 packaging. Confirm RoHS compliance status as indicated in official documentation. Check for obsolescence notices or limited availability status directly from Analog Devices or authorized distributors before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 2.88 V threshold is required for 3.3 V or 5 V logic systems. Ensure the open-drain output configuration matches the downstream circuit requirements. Verify that the 100 ms minimum reset timeout meets the target processor's initialization timing constraints.

Supervisors Part Context

This part belongs to the Maxim Integrated EconoReset family, designed for cost-sensitive applications. It complements other variants like the DS1818R-20 (2.55 V threshold) and through-hole versions such as the DS1818-5. The R-10 designation specifically identifies the voltage threshold and surface-mount package type within the broader DS1818 product line.
