DataSheet.in 19-3582; Rev 1; 5/06 Overvoltage Protection Controllers with Reverse Polarity Protection General Description 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 complementary MOSFET. If the input voltage exceeds the overvoltage threshold, these devices turn off the n-channel MOSFET to prevent damage to the protected components. If the input voltage drops below ground, the devices turn off the p-channel MOSFET to prevent damage to the protected components. An internal charge pump eliminates the need for external capacitors and drives the MOSFET GATEN for a simple, robust solution.
