What this part does — overvoltage and undervoltage protection in a single IC
The Analog Devices MAX17613CATP+ is a current-limiting, overvoltage and undervoltage protection IC in a 4x4 mm package. It monitors the input rail and disconnects the load when voltage exceeds or drops below programmed thresholds, protecting downstream circuitry from supply faults. The part handles a supply range of 4.5V to 60V and draws 880µA quiescent current, making it suitable for always-on protection in industrial, automotive, and telecom equipment where the rail can swing outside safe limits.
The 60V maximum supply voltage means this part can sit directly on a 48V telecom bus, a 24V industrial rail with transients, or a 12V automotive line without needing a pre-regulator.
The wide temperature grade means no derating headache when the enclosure sits in direct sun or near a motor drive.
