MAX4867 - Overvoltage Protection Controllers

Download the MAX4867 datasheet PDF. This datasheet also covers the MAX4864L variant, as both devices belong to the same overvoltage protection controllers family and are provided as variant models within a single manufacturer datasheet.

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.

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.
