ADM1815-R22ART-RL7

Supervisors Overview

The ADM1815-R22ART-RL7 is a microprocessor reset circuit manufactured by Analog Devices Inc. It functions as a voltage supervisor with a fixed threshold of 2.18V, designed to monitor power supply voltages such as 2.5 V, 3 V, 3.3 V, and 5 V systems. The device provides a reset output signal when the monitored voltage drops below the specified threshold, ensuring proper system initialization. It operates within a temperature range of -40°C to +85°C and is housed in an SOT-23 package.

Supervisors Feature Summary

• Provides reliable voltage monitoring for standard logic supply levels
• Generates a reset signal upon undervoltage conditions
• Suitable for low-cost embedded applications

Supervisors Applications

• Embedded microprocessor systems
• Industrial HMI interfaces
• Edge computing devices

Supervisors Procurement Notes

Verify the exact suffix 'R22' corresponds to the 2.18V threshold variant during procurement. Confirm the 'ARTZ' or 'RL7' packaging details match specific reel requirements. Check current availability status as distribution may vary. Ensure compatibility with the target board's thermal and electrical specifications before finalizing orders.

Supervisors Selection Notes

Select this component when a fixed 2.18V supervision threshold is required for standard voltage rails. It is appropriate for designs needing simple undervoltage protection without adjustable thresholds. Consider the SOT-23 footprint constraints and operating temperature range relative to the application environment.

Supervisors Part Context

This part belongs to the ADM1815 series of supervisory circuits from Analog Devices. These components are widely used for protecting microprocessors and memory devices from power failures. The series offers various threshold options to accommodate different logic families and supply voltages commonly found in industrial and consumer electronics.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the ADM1815 family that offer different threshold voltages if the 2.18V level is unsuitable. Verify functional equivalence with other manufacturers' voltage supervisors offering similar reset timing and package types.
