DS1818-5+T&R

Supervisors Overview

The DS1818-5+T&R is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of up to 5.5 V and features a threshold voltage of 3.06 V. The device provides manual reset functionality with an active low, open drain output type. It includes power failure detection capabilities but lacks a watchdog timer or battery backup switch. The component supports through-hole installation in a TO-92-3 package and functions reliably across a temperature range from -40 °C to +85 °C.

Supervisors Feature Summary

• Provides manual reset capability for system control
• Detects power failure events automatically
• Features active low open drain output configuration

Supervisors Applications

• Embedded systems requiring manual reset inputs
• Power supply monitoring circuits
• Industrial control units needing voltage supervision

Supervisors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm package type and electrical characteristics. Confirm availability status as distribution channels may list this item as discontinued or limited stock. Ensure the ordering part number matches the required through-hole TO-92-3 form factor rather than surface mount variants.

Supervisors Selection Notes

Select this component when a manual reset input is required alongside basic voltage supervision. The through-hole TO-92-3 package suits prototyping or legacy board designs. Verify that the 3.06 V threshold aligns with the target system voltage rails. Consider alternative packages if surface mount assembly is necessary for production.

Supervisors Part Context

This part belongs to the EconoReset series of supervisory circuits designed for simple voltage monitoring applications. It integrates essential reset generation and power fail detection into a compact three-pin package. The series focuses on cost-effective solutions for basic system protection without complex digital interfaces or programmable thresholds.

Supervisors Replacement Considerations

DS1818R-5+T&R offers similar functionality in a surface-mount SOT-23-3 package.
