• Voltage supervision for 2.5 V logic circuits
• Power-on reset timing control

Supervisors Procurement Notes

Verify the exact suffix ART-REEL to confirm reel packaging and specific threshold voltage. Confirm current availability status as distribution channels may list this component as obsolete or limited stock. Ensure the 2.55 V threshold matches the target application requirements before procurement.

Supervisors Selection Notes

Select this part when a fixed 2.55 V threshold is required for systems operating at or below 5.5 V. The SOT-23-3 package suits space-constrained designs. Verify that the 250 ms reset delay meets the system's startup timing constraints. Compare against other ADM1817 variants if different threshold voltages are needed.

Supervisors Part Context

This component belongs to the ADM1817 family of microprocessor reset circuits from Analog Devices. These devices are designed to monitor single power supplies and generate a reset signal when the voltage drops below a specified threshold. The family offers various threshold options to accommodate different logic families and supply voltages.
