Procurement Notes

Verify the specific manufacturer part number against official ABLIC documentation to ensure authenticity and correct revision status. Confirm that the required threshold voltage and output type align with the system design requirements before procurement. Check for any regional distribution restrictions or RoHS compliance documentation updates from the supplier. Ensure that the ordering suffix matches the desired packaging format if applicable.

Selection Notes

Select this component when a precise 1.8 V detection threshold is required for single-channel supervision. The open-drain output necessitates an external pull-up resistor; verify circuit compatibility with the target logic voltage levels. Consider the 350 nA quiescent current for energy-sensitive designs. The SOT-23-5 footprint requires adequate thermal and mechanical clearance on the printed circuit board layout.
