Linear Technology/Analog Devices’ LT8672HMSPBF is an active rectifier controller for reverse input protection. This controller drives an external N-channel MOSFET to replace a power Schottky diode. Its very low quiescent current and fast transient response meet the tough requirements in automotive applications where AC input signals of up to 100 kHz are present. These signals are rectified with minimum power dissipation on the external FET, simplifying thermal management on the PCB.
