MAX4865 Overview
The MAX4864L/MAX4865L/MAX4866L/MAX4867/ MAX4865/MAX4866 overvoltage protection controllers protect low-voltage systems against high-voltage faults up to +28V, and negative voltages down to -28V. These devices drive a low-cost plementary MOSFET. If the input voltage exceeds the overvoltage threshold, these devices turn off the n-channel MOSFET to prevent damage to the protected ponents.
