Overview
The LTC4366HTS8-2#TRPBF, produced by Analog Devices Inc., is a high voltage surge stopper designed to protect loads from high voltage transients. This device controls the gate of an external N-channel MOSFET to regulate the output during overvoltage transients, ensuring the load remains operational while the excess voltage is dropped across the MOSFET. It features an adjustable overvoltage timer and a cool-down period to prevent MOSFET damage, making it a robust solution for surge protection in various applications.
