Supervisors Procurement Notes

Verify the specific suffix against official datasheets to confirm functional variations, as different suffixes may indicate distinct package types or temperature ranges. Ensure compatibility with existing PCB footprints and validate that the 36 V maximum rating aligns with system requirements. Confirm RoHS compliance status through manufacturer documentation before integration.

Supervisors Selection Notes

Select this component when high-voltage input monitoring is required alongside battery backup support. The 85 ms delay helps filter transient noise, while the low quiescent current suits energy-constrained applications. Verify that the open-drain output interface matches the downstream logic requirements and that the SOT-23-5 package fits the design constraints.
