LT8672HDDB#TRPBF

Overview

The LT8672HDDB#TRPBF is an active rectifier controller with reverse protection, manufactured by Analog Devices Inc. It drives an external N-channel MOSFET to replace a power Schottky diode, offering superior efficiency in mixed-voltage systems where control logic operates at 3.3V or 5V while gate drive swings up to 24V or higher. The device supports a supply voltage range of 3V to 42V and is housed in a 10-DFN (3x2) package.
