DS1813R-15/T&R

Supervisors Overview

The DS1813R-15/T&R is a supervisory circuit from the EconoReset family, designed to monitor power supply status in electronic systems. It features a single monitored input with a threshold voltage of 4.13 V and an overvoltage threshold of 4.49 V. The device provides an active low open-drain output and includes a reset delay time of 100 ms minimum. Operating within a supply voltage range up to 5.5 V, it maintains an accuracy of 2.5% and draws a typical operating current of 40 uA. The component supports surface mount installation in a SOT-23-3 package and functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Monitors power supply voltage using a precision reference and comparator circuit
• Generates internal power-fail signal when out-of-tolerance conditions are detected
• Provides active low open-drain reset output for system control

Supervisors Applications

• Microprocessor system supervision
• Power supply monitoring in embedded controllers
• Voltage threshold detection in industrial electronics

Supervisors Procurement Notes

Verify the specific suffix T&R indicates tape and reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates before procurement. Ensure the sourcing channel provides valid traceability for Analog Devices Inc./Maxim Integrated components to guarantee authenticity and quality standards.

Supervisors Selection Notes

Select this component when a simple, low-cost supervisor with fixed threshold monitoring is required. The SOT-23-3 package suits space-constrained designs. Verify that the 4.13 V threshold aligns with the target system's voltage tolerance requirements. Consider the absence of manual reset functionality if user intervention is necessary during operation.
