ADM1818-10ART-REEL

Supervisors Overview

The ADM1818-10ART-REEL is a microprocessor reset circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.63V to 5.5V and features a fixed reset threshold of 2.88V. The device provides a push-pull or图腾柱 output configuration with an active-high reset signal. It includes a programmable reset timeout period, with a minimum specified duration of 140ms. The component is designed for surface-mount installation in SOT-23-3 packages and supports operation across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides reliable system reset generation for microprocessors and digital logic circuits
• Features a fixed reset threshold voltage ensuring consistent monitoring performance
• Includes a programmable reset timeout to accommodate various startup requirements

Supervisors Applications

• Microprocessor system supervision
• Digital logic circuit protection
• Embedded system power management

Supervisors Procurement Notes

Verify the specific suffix ART-REEL confirms the tape-and-reel packaging format required for automated assembly processes. Confirm the device status as discontinued or limited availability through official Analog Devices channels prior to finalizing procurement plans. Ensure compatibility with existing board layouts regarding the SOT-23-3 footprint and pinout configuration.

Supervisors Selection Notes

Select this component when a fixed 2.88V threshold is appropriate for the target supply rail. Consider the 140ms minimum timeout requirement against system startup timing constraints. Evaluate the SOT-23-3 package size against available PCB real estate. Verify that the active-high output polarity aligns with the receiving logic interface requirements.

Supervisors Part Context

This part belongs to the ADM81x series of simple reset supervisors from Analog Devices. These devices are designed to monitor a single voltage rail and generate a reset signal when the voltage drops below a specific threshold. The series typically offers various threshold options and timeout configurations to suit different application needs.

Supervisors Replacement Considerations

Check for direct replacements within the ADM81x family such as ADM810 or ADM809 variants if threshold or package differences are acceptable. Verify functional equivalence regarding output type and timeout characteristics before substitution.
