ADM1818-20AKS-REEL

Supervisors Overview

The ADM1818-20AKS-REEL is a microprocessor reset circuit designed for monitoring power supply voltages. It provides a reliable reset output with a typical threshold level of 2.55 V, suitable for 2.5 V, 3 V, 3.3 V, and 5 V systems. The device includes an optional push-button reset function to allow manual system resets. It operates within a specified temperature range and is packaged in a small outline package.

Supervisors Feature Summary

• Provides a dedicated reset output signal triggered by specific voltage thresholds
• Includes an integrated push-button reset capability for manual intervention
• Designed for low-cost voltage monitoring applications

Supervisors Applications

• Microprocessor reset circuits
• Voltage monitoring for embedded systems
• Power supply supervision in industrial control

Supervisors Procurement Notes

Verify the exact threshold voltage specification (2.55 V) against the official datasheet before integration. Confirm that the REEL suffix matches your automated assembly requirements. Ensure the operating temperature range meets your environmental specifications. Cross-reference the pinout with your PCB layout to avoid connection errors during procurement and assembly.

Supervisors Selection Notes

Select this component when a fixed 2.55 V threshold is required for system supervision. Consider the ADM1818 series if a push-button reset feature is necessary alongside automatic power-on reset functionality. Evaluate the package size constraints as it utilizes a small outline package. Compare against other ADM181x variants if different threshold voltages are needed for alternative supply rails.

Supervisors Part Context

The ADM1818 belongs to Analog Devices' family of low-cost voltage monitoring devices. It is part of the ADM1810–ADM1818 series, which offers various threshold options. This specific variant targets applications requiring precise supervision of lower voltage rails common in modern digital logic.

Supervisors Replacement Considerations

Direct substitutes include other ADM1818 variants with different threshold voltages or package types, such as ADM1818-20ART-REEL. Check datasheets for compatible alternatives within the ADM181x series that match the required reset threshold and interface.
