General Description

The MAX14586/MAX14590 overvoltage protection devices feature a low 48mI (typ) on-resistance (RON) internal FET and protect low-voltage systems against voltage faults up to +36V. When the input voltage exceeds the overvoltage threshold, the internal FET is turned off to prevent damage to the protected components.
