ADM1811-10ART-RL7

Supervisors Overview

The ADM1811-10ART-RL7 is a voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range up to 5.5 V and features an open-drain output with an internal pull-up resistor. The device provides a reset signal with a typical delay of 250 ms. It is available in a SOT-23-3 surface-mount package and supports threshold voltages including 4.35 V and 4.62 V. The component is designed for monitoring single input lines without manual reset or watchdog timer functionality.

Supervisors Feature Summary

• Provides active low reset signal generation based on monitored supply voltage levels
• Features open-drain output configuration with integrated internal pull-up resistor
• Operates as a dedicated voltage supervisor without manual reset controls

Supervisors Applications

• Microprocessor reset circuitry
• Voltage supervision for embedded systems
• Power management monitoring

Supervisors Procurement Notes

Verify current availability status as the component may be discontinued or subject to limited supply conditions. Confirm exact ordering suffixes such as -RL7 versus -REEL against official manufacturer documentation to ensure correct packaging and revision. Cross-reference datasheet specifications with design requirements before procurement.

Supervisors Selection Notes

Select this component when a simple voltage supervisor with open-drain output is required. Ensure the application voltage does not exceed the maximum rating of 5.5 V. Verify that the specific trip point options, such as 4.35 V or 4.62 V, align with system thresholds. Consider the SOT-23-3 package constraints for PCB layout.

Supervisors Part Context

This part belongs to the ADM1811 series of microprocessor reset circuits from Analog Devices. The series includes variants with different output types and trip points. The ADM1811 specifically utilizes an open-drain output structure, distinguishing it from push-pull variants like the ADM1817. It serves as a fundamental building block for power-on reset functions in digital logic designs.

Supervisors Replacement Considerations

Direct substitute options include the ADM1811-10ARTZ-RL7. Verify pin compatibility and electrical specifications before substitution. Check for any changes in manufacturing status or package revisions between original and replacement parts.
