The Analog Devices MAX17612CATB+T is an overvoltage and undervoltage protection IC that sits between your supply rail and the downstream circuitry. Its 4.5V to 60V input range covers common automotive and industrial bus voltages — 12V, 24V, and 48V nominal rails — without needing a separate pre-regulator. The 890 µA supply current is low enough to leave on the rail continuously for fault monitoring without burning standby budget.
Temperature grade and package — where it survives
The 10-TDFN (3x3 mm) exposed pad package requires a thermal via stitch under the pad for heat dissipation.
