Supervisors Procurement Notes

Verify the exact suffix D3+ indicates lead-free status and RoHS compliance when ordering. Confirm the UK26 designation matches the required 2.63V threshold for your specific application design. Ensure the SOT23-5 package fits your PCB layout constraints. Cross-reference the manufacturer's latest datasheet for any updates on recommended operating conditions or handling precautions before finalizing procurement.

Supervisors Selection Notes

Select this component when a fixed 2.63V threshold is required for system supervision. Consider the manual reset feature if external user intervention is needed during operation. Evaluate the low quiescent current against total system power budgets. Verify compatibility with the target logic levels due to the open-drain output structure. Compare alternative thresholds if the 2.63V setting does not align with the monitored rail voltage.

Supervisors Part Context

This part belongs to the MAX685x family of microprocessor supervisory circuits. These devices are engineered to monitor voltage rails and generate reset signals upon detecting out-of-range conditions. The family typically offers multiple threshold options and package variations to suit different form factors. The MAX6854 specifically integrates a manual reset function alongside standard voltage monitoring capabilities.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the same MAX685x series that offer similar threshold voltages. Verify that substitute parts maintain the same open-drain output configuration and manual reset functionality. Ensure replacement components meet the same operating temperature ranges and supply voltage specifications as the original part.
