DS1811-10+T&R

Supervisors Overview

The DS1811-10+T&R is a voltage monitor supervisor circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of up to 5.5 V and features an active low, open drain output. The device monitors a single input with a threshold voltage of 4.35 V and an overvoltage threshold of 4.49 V. It provides a reset delay time of 150 ms and maintains an accuracy of 2.5%. The component functions in temperatures from -40°C to +85°C, consumes 40 uA of operating current, and lacks manual reset, watchdog timer, or battery backup capabilities.

Supervisors Feature Summary

• Provides power-failure detection for system supervision
• Features an open-drain output compatible with various logic families
• Operates without requiring external components for basic monitoring

Supervisors Applications

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

Supervisors Procurement Notes

Verify the exact suffix designation against official manufacturer documentation, as the provided model references a reel format while datasheets often specify tape-and-reel packaging. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the specific batch matches the required operating temperature range and electrical specifications for your design.

Supervisors Selection Notes

Select this component when a simple, low-power voltage supervisor with an open-drain output is required. It is suitable for applications needing a fixed threshold near 4.35 V without complex configuration options. Consider alternative packages if surface-mount space is limited, as it utilizes a SOT-23-3 package.

Supervisors Part Context

This part belongs to the EconoReset series, designed for cost-effective power management solutions. It serves as a fundamental supervisory element in electronic designs where reliable power-on reset and brown-out protection are necessary without adding significant bill-of-materials complexity.

Supervisors Replacement Considerations

Consult official substitution guides for equivalent supervisors with similar thresholds and output types. Verify pin compatibility and electrical characteristics before replacing.
