Supervisors Procurement Notes

Verify the specific suffix TR-FE confirms the reel packaging format and tape-and-reel quantity requirements for your assembly line. Confirm that the SOT-23-5 footprint matches your PCB design guidelines. Ensure the 2.2 V threshold aligns with your system's brown-out protection specifications before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed 2.2 V threshold is required for single-channel voltage monitoring. It is appropriate for designs prioritizing ultra-low power consumption alongside standard CMOS output compatibility. Consider the integrated backup feature if maintaining voltage history during power cycles is critical for your application logic.
