Industrial temperature and package reality
Rated for -40°C to 85°C ambient, this part handles the thermal swings you see in outdoor telecom enclosures, factory automation panels, and automotive cabin modules. The SOT-23-3 package (TO-236-3, SC-59 equivalent) is a three-pin surface-mount footprint that fits into tight layouts alongside passives — no extra board area for a larger SOIC. The single monitored voltage means this is a straightforward rail guard, not a multi-voltage sequencer; you place it on the core or I/O supply and route the reset output to the processor's /RST pin.
Active lifecycle — no LTB pressure
This removes the sourcing risk of a last-time-buy scramble — you can qualify it into a new BOM without worrying about a short procurement window. The part is available through independent distribution, quoted to order against an RFQ with current pricing confirmed at quote time.
