DS1818R-5+T&R

Supervisors Overview

The DS1818R-5+T&R is a single-channel voltage supervisor integrated circuit from the EconoReset series, manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 3.06 V for power monitoring. The device provides an active-low reset signal with an open-drain or open-collector output configuration. It includes a minimum reset timeout delay of 100 ms to ensure stable system initialization. The component supports surface-mount installation in a compact SOT-23-3 package and functions reliably across an extended industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

Supervisors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and electrical characteristics. Ensure the selected variant matches the required operating temperature range and output configuration for your specific application design constraints.

Supervisors Selection Notes

Select this component when a low-cost, single-channel supervisory solution is required for systems operating near 3.3 V or 5 V rails. Consider the open-drain output requirement for pull-up resistor implementation and verify that the 100 ms minimum timeout meets the target processor's startup timing requirements.

Supervisors Part Context

This part belongs to the DS1818 family of voltage supervisors designed for cost-sensitive applications. It serves as a fundamental building block for ensuring reliable system resets in embedded designs where precise voltage monitoring is critical for preventing erratic behavior during power transitions.

Supervisors Replacement Considerations

Consult official cross-reference guides for verified substitutes such as other variants within the DS1818 series or equivalent single-channel supervisors from Analog Devices/Maxim Integrated that match the SOT-23-3 footprint and 3.06 V threshold.
