DS1813R-5+T&R

Supervisors Overview

The DS1813R-5+T&R is a single-channel voltage supervisor from the EconoReset series, manufactured by Analog Devices Inc./Maxim Integrated. It monitors one supply voltage with a threshold of 4.62V and features an active-low open-drain output. The device provides a minimum reset timeout of 100ms to ensure system stability during power transitions. It operates within a temperature range of -40°C to +85°C and is housed in a surface-mount SOT-23-3 package.

Supervisors Feature Summary

• Monitors a single power supply rail for out-of-tolerance conditions
• Generates an active-low reset signal upon detecting power failure
• Includes manual pushbutton reset functionality via the reset output pin

Supervisors Applications

• Microprocessor and microcontroller system supervision
• Power sequencing in embedded systems
• Battery-powered devices requiring reliable power monitoring

Supervisors Procurement Notes

Verify the exact suffix against official manufacturer documentation to confirm package type and electrical characteristics. Ensure compatibility with existing PCB footprints for the SOT-23-3 package. Confirm RoHS compliance status if required by specific regulatory standards. Cross-reference part numbers carefully as variations may exist between distributors.

Supervisors Selection Notes

Select this component when a simple, low-cost solution for single-voltage monitoring is required. The open-drain output allows for flexible interfacing with various logic levels. Consider the manual reset feature if user intervention is needed for system recovery. Verify that the 4.62V threshold aligns with the target supply voltage requirements.

Supervisors Part Context

This part belongs to the DS1813 family of supervisory circuits designed for cost-sensitive applications. It shares functional similarities with other EconoReset devices but differs in threshold voltage and packaging. The R-5 suffix typically denotes the specific voltage threshold and reel packaging configuration.

Supervisors Replacement Considerations

Direct substitutes include other DS1813 variants with different thresholds or packages. Check datasheets for equivalent performance in terms of reset delay and operating temperature range.
