Supervisors Procurement Notes

Verify the specific suffix 'ATEC' against official Analog Devices documentation to confirm the exact pinout and feature set, as variations exist within the family. Ensure the component meets ASIL B compliance requirements for your specific safety integrity level needs. Confirm availability status, as supply may be restricted. Validate that the 16-SW-TQFN package with wettable flanks matches your PCB assembly capabilities.

Supervisors Selection Notes

Select this component when a multi-channel supervisor with mixed single-ended and differential inputs is required. It is suitable for designs needing ASIL B certification without integrating full microcontroller complexity. Consider the seven available threshold options to minimize external resistor networks. Ensure the operating temperature range aligns with the harsh environment of the target automotive application.
