DS1813R-15+T&R

Supervisors Overview

The DS1813R-15+T&R is a single-channel power supply support circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a temperature range of -40°C to +85°C and utilizes a SOT-23-3 surface-mount package. The device features a fixed threshold voltage of 4.13V and provides an open-drain or open-collector output. It generates a low-active reset signal with a minimum timeout duration of 100ms upon detecting out-of-tolerance power supply conditions.

Supervisors Feature Summary

• Monitors power supply status using a precision temperature reference and comparator circuit
• Generates internal power-fail signals when voltage exceeds tolerance limits
• Maintains reset active state for stabilization period after voltage recovery

Supervisors Applications

• Microprocessor system supervision
• Power supply monitoring in embedded systems
• Reset generation for digital logic circuits

Supervisors Procurement Notes

Verify the manufacturer designation as Analog Devices Inc./Maxim Integrated on official documentation. Confirm the specific suffix T&R indicates tape and reel packaging. Ensure the part number matches the exact threshold voltage specification required for the application design.

Supervisors Selection Notes

Select this component when a fixed 4.13V threshold is appropriate for the target power rail. The open-drain output requires external pull-up configuration. Consider the SOT-23-3 package constraints for PCB layout and thermal management requirements within the specified operating temperature range.

Supervisors Part Context

This component belongs to the EconoReset series, designed for cost-effective power supply supervision. It replaces older discrete monitoring solutions by integrating reference and comparator functions into a compact three-pin package suitable for space-constrained designs.
