ADM1817-10ART-REEL

Supervisors Overview

The ADM1817-10ART-REEL is a voltage monitoring circuit from the ADM181x family, designed to reset electronic systems when supply voltages drop below specified thresholds. It supports monitoring of 2.5 V, 3 V, 3.3 V, and 5 V power rails. The device features a fixed reset threshold level of 4.62 V. It is housed in a SOT-23-3 surface-mount package and operates within a standard industrial temperature range.

Supervisors Feature Summary

• Provides reliable low-cost voltage monitoring with a dedicated reset output
• Suitable for supervising multiple standard power supply voltages including 2.5 V, 3 V, 3.3 V, and 5 V
• Fixed reset threshold level ensures consistent system protection without external components

Supervisors Applications

• Microprocessor reset circuits requiring voltage supervision
• Battery-powered systems needing under-voltage detection
• Portable equipment utilizing 3 V or 3.3 V logic supplies

Supervisors Procurement Notes

Verify the specific suffix ART-REEL indicates tape and reel packaging configuration. Confirm the manufacturer is Analog Devices Inc. Ensure the part number matches the exact 4.62 V threshold variant. Check current availability status as distribution may vary by region.

Supervisors Selection Notes

Select this component when a fixed 4.62 V threshold is required for system reset. Compare against other ADM181x variants if different threshold levels such as 2.55 V or 2.88 V are needed. Consider the SOT-23-3 package size constraints for PCB layout.

Supervisors Part Context

This part belongs to the ADM181x series of voltage supervisors. These ICs are designed for applications where an electronic system must be reset upon loss of power or brown-out conditions. The series offers various threshold options to accommodate different logic families and supply voltages.

Supervisors Replacement Considerations

Check for ADM1817-20ART-REEL (2.55 V threshold) or ADM1817-25ART-REEL (2.88 V threshold) if lower thresholds are acceptable. Verify pinout compatibility with SOT-23-3 packages before substitution.
