# LM74610QDGKRQ1 (Component) ## Description OR Controller N+1 ORing Controller N-Channel N:1 8-VSSOP The LM74610QDGKRQ1 is an automotive-qualified smart bypass ideal diode controller designed to drive an external N-channel MOSFET for reverse polarity protection and input supply OR-ing applications. The device minimizes forward voltage drop and power dissipation compared to traditional Schottky diodes while providing robust protection against reverse battery conditions. It supports operation across a wide automotive input voltage range and is optimized for high-current systems requiring low standby current, fast response, and reliable transient handling. The device is AEC-Q100 qualified for automotive applications and is commonly used in ECU power distribution, battery protection, and redundant supply systems.
