DS1812R-15/T&R

Supervisors Overview

The DS1812R-15+T&R is a single-channel voltage supervisor from the EconoReset series, manufactured by Analog Devices Inc./Maxim Integrated. It provides a simple reset or power-on reset function with a push-pull/totem pole output and active-high reset signal. The device monitors one voltage channel with a threshold of 4.36V and features a minimum reset timeout of 100ms. It operates within a temperature range of -40°C to +85°C (TA) and is available in a surface-mount SOT-23-3 package.

Supervisors Feature Summary

• Provides system reset functionality via a dedicated supervision channel
• Features an active-high reset signal with push-pull output drive
• Includes a minimum reset timeout delay for stable power-up sequencing

Supervisors Applications

• Microprocessor system monitoring
• Power supply supervision
• Embedded controller reset generation

Supervisors Procurement Notes

Verify the exact part number suffix against official manufacturer documentation to confirm electrical characteristics such as threshold voltage and output type. Ensure the component matches the required operating temperature range and package configuration for the specific application design before procurement.

Supervisors Selection Notes

Select this component when a single-channel voltage supervision with an active-high output is required. Consider the 4.36V threshold and 100ms timeout duration relative to the monitored rail's stability requirements. Verify compatibility with the target logic family and ensure the SOT-23-3 package fits the board layout constraints.

Supervisors Part Context

This component belongs to the DS1812 series of voltage supervisors designed for cost-sensitive applications. It offers basic reset generation capabilities without complex programmability, serving as a fundamental protection element in digital systems requiring reliable power management and reset sequencing.

Supervisors Replacement Considerations

Consult official substitution lists for compatible parts within the same series or equivalent functional alternatives. Verify that any substitute maintains identical threshold voltages, output polarity, and package dimensions to ensure seamless integration.
