ADM1817-20AKS-REEL

Supervisors Overview

The ADM1817-20AKS-REEL is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It provides a reset signal for systems operating with supply voltages up to 5.5V, featuring a fixed output threshold of 2.93V. The device incorporates a manual reset input and an open-drain active-low reset output. It operates within a temperature range of -40°C to +85°C and is housed in an 8-pin SOIC package.

Supervisors Feature Summary

• Fixed voltage monitoring threshold at 2.93V
• Manual reset capability via dedicated input pin
• Open-drain reset output configuration

Supervisors Applications

• Microprocessor power supply monitoring
• Battery-powered system supervision
• Embedded controller reset generation

Supervisors Procurement Notes

Verify the suffix 'KS' indicates specific reel packaging or tape-and-reel configuration as per manufacturer documentation. Confirm the 'A' grade designation aligns with required temperature and accuracy specifications. Ensure the 8-SOIC package dimensions match the target PCB footprint. Cross-reference the exact part number against current Analog Devices inventory lists to confirm availability status.

Supervisors Selection Notes

Select this component when a fixed 2.93V threshold is required for low-voltage digital logic families. The manual reset feature allows for external user-initiated system resets. Consider the open-drain output requirement for pull-up resistor implementation. Verify that the 8-SOIC package is suitable for the assembly process and thermal management requirements of the application.

Supervisors Part Context

This part belongs to the ADM1817 series of supervisory circuits designed for reliable system management. It complements other voltage monitors in the portfolio offering different thresholds and features like watchdog timers. The series supports various industrial and commercial applications requiring precise voltage tracking without complex external components.

Supervisors Replacement Considerations

Direct substitutes include ADM1817 variants with different voltage thresholds (e.g., ADM1817-30) if the monitoring level differs. Other ADM18xx series parts may offer similar functionality but require verification of pin compatibility and electrical parameters.
