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 simple reset or power-on-reset functionality with a low-active output and an open-drain/open-collector configuration. The device monitors one supply voltage with a threshold of 4.13V and ensures a minimum reset timeout of 100ms. It operates within a temperature range of -40°C to +85°C and is available in a surface-mount SOT-23-3 package.

Supervisors Feature Summary

• Provides active-low reset signal generation for monitored power rails
• Features open-drain or open-collector output stage for flexible interfacing
• Ensures system stability with a guaranteed minimum reset timeout duration

Supervisors Applications

• Microprocessor and microcontroller power supply monitoring
• Battery-powered equipment requiring reliable power supervision
• Embedded systems needing simple reset circuitry

Supervisors Procurement Notes

Verify the specific suffix 'R-15' corresponds to the 4.13V threshold and low-active logic level required for your design. Confirm that the open-drain output compatibility matches your target system's input requirements. Ensure the SOT-23-3 footprint aligns with your PCB layout specifications before finalizing procurement.

Supervisors Selection Notes

Select this component when a low-active reset signal is preferred over high-active outputs. The open-drain output allows for wired-OR configurations or level shifting if necessary. Consider the 4.13V threshold against your nominal supply voltage to ensure proper triggering during brown-out conditions.

Supervisors Part Context

This part belongs to the DS1812 family of voltage supervisors designed for cost-sensitive applications. It offers basic reset functionality without complex programmability, making it suitable for standard digital logic circuits where a dedicated supervisor IC is needed but advanced features are unnecessary.

Supervisors Replacement Considerations

Check for other variants within the DS1812 series that may offer different voltage thresholds or active-high outputs if the current specification does not match the design requirements exactly.
