## Description

The LT4363CDE-2#TRPBF is an overvoltage protection regulator from Analog Devices that drives an external N-channel MOSFET to protect load circuitry from high voltage surges. It operates from a wide supply voltage range of 4V to 80V and can withstand voltages down to -60V without damage. The device features an internal charge pump for efficient MOSFET control and includes an active current limit circuit.

Key features include adjustable current limiting, with typical limits of 50mV above 2V output and 25mV during severe shorts. A fault timer varies with the MOSFET voltage, helping to keep the MOSFET within its safe operating area during transient events. The device also supports a reset time of at least 100µs with a slew rate of at least 10V/ms.

This surge stopper is suitable for applications requiring protection against short-duration high voltage transients, such as those found in automotive environments. It can be used to replace inline Schottky diodes for reverse input protection, improving efficiency and available supply voltage during cold crank conditions.
