LM74670-Q1 Smart Diode Rectifier ControllerTexas Instruments LM74670-Q1 Smart Diode Rectifier Controller is a controller device that can be used with an N-Channel MOSFET in full or half-bridge rectifier architectures for alternators. This is designed to drive an external MOSFET to emulate an ideal diode. A unique advantage of this scheme is that it is not ground referenced, thus, it has zero I Q. The schottky diodes in full or half-bridge rectifiers and alternators can be replaced with the LM74670-Q1 solution to avoid forward conduction diode losses and produce more efficient AC-DC converters. The LM74670-Q1 controller provides a gate drive for external N-Channel MOSFET and a fast response internal comparator to pull down the MOSFET Gate in the event of reverse polarity. This device can support an AC signal frequency up to 300Hz.
