What this part is and where it fits
The MAX14722ATP+ from Analog Devices is an adjustable current-limit IC with integrated overvoltage and undervoltage protection, built for systems that need to survive a wide input rail. The 5.5 V to 58 V supply range covers industrial buses, automotive battery lines, and telecom backplanes. The 1.4 mA supply current is low enough to leave on continuously in a protection front-end without draining the system's standby budget. The -40°C to 125°C operating range qualifies it for under-hood automotive, outdoor industrial enclosures, and engine-bay-adjacent electronics. The 20-TQFN (4x4) package with exposed pad pulls heat into the board's ground plane — plan a thermal via array under the pad if you're running near the current limit at high ambient.
Sourcing and lifecycle
The MAX14722ATP+ is listed as Active and ROHS3 compliant. No last-time-buy notice, no NRND flag — it's a current-production part you can qualify into a new BOM without worrying about an imminent EOL.
