DS1811R-10+T&R

Supervisors Overview

The DS1811R-10+T&R is a voltage monitor supervisory 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 single monitored input with a threshold voltage of 4.35 V. The device provides an active low, open drain output and includes a reset delay time of 150 ms. It exhibits a power failure detection capability and maintains an accuracy of 2.5%. The component functions in temperatures ranging from -40°C to +85°C, drawing a typical operating current of 40 uA.

Supervisors Feature Summary

• Provides power-failure detection for system monitoring
• Features an active low open-drain output configuration
• Includes a fixed 150 ms reset delay timer

Supervisors Applications

• Embedded systems requiring voltage supervision
• Microcontroller power management circuits
• Industrial control board monitoring

Supervisors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical characteristics and package type. Ensure compatibility with the target PCB footprint and thermal requirements. Confirm RoHS compliance status through authorized channels prior to integration into production designs.

Supervisors Selection Notes

Select this component when a simple, low-power voltage supervisor with an open-drain output is required. The fixed threshold and delay simplify design without external components. Consider alternative models if manual reset or watchdog functionality is needed, as this part lacks those features.

Supervisors Part Context

This part belongs to the DS1811R series of EconoReset supervisors. It is designed for cost-sensitive applications requiring basic power monitoring. The SOT-23-3 package allows for compact surface-mount installation on space-constrained printed circuit boards.

Supervisors Replacement Considerations

Consult official substitution guides for compatible parts within the same family. Verify pinout and electrical parameter alignment before replacing.
