DS1813R-10/T&R

Supervisors Overview

The DS1813R-10+T&R is a supervisory circuit from the EconoReset family, designed to monitor a single power supply input. It features an active-low open-drain output and includes a manual reset pushbutton option. The device operates within a voltage range of 4.75V to 5.5V with a threshold of 4.35V. It provides a typical reset delay of 150ms and maintains accuracy within 2.5%. Operating temperatures span from -40°C to +85°C, housed in a SOT-23-3 package.

Supervisors Feature Summary

• Integrates a precision temperature reference and comparator for accurate power monitoring
• Includes a manual reset function activated by pulling the output low via a pushbutton
• Generates an internal power-fail signal when supply voltage exceeds tolerance limits

Supervisors Applications

• Microprocessor system supervision
• Power supply monitoring in embedded controllers
• Manual reset implementation in industrial control units

Supervisors Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout and functional variations. Ensure the ordering code matches the required package type and tape-and-reel specifications. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and current production status before procurement.

Supervisors Selection Notes

Select this component for applications requiring a simple, low-cost supervisor with manual reset capability. It is suitable for systems needing a fixed threshold near 4.35V. Consider the open-drain output compatibility with the target logic levels. Verify that the SOT-23-3 package fits the available board space constraints.

Supervisors Part Context

This part belongs to the Maxim Integrated EconoReset series, which focuses on cost-effective power management solutions. The DS1813 variant specifically adds manual reset functionality compared to standard supervisors. It serves as a reliable alternative for basic power sequencing and fault detection in consumer and industrial electronics.

Supervisors Replacement Considerations

Consult official substitution guides for compatible parts within the DS181x series or equivalent supervisory circuits from other manufacturers. Ensure replacement components match the SOT-23-3 footprint and electrical characteristics.
