Information

The LM74610-Q1 is a controller device that can be used with an N-Channel MOSFET in a reverse polarity protection circuitry. It is designed to drive an external MOSFET to emulate an ideal diode rectifier when connected in series with a power source. A unique advantage of this scheme is that it is not referenced to ground and thus has Zero Iq.

The LM74610-Q1 controller provides a gate drive for an external N-Channel MOSFET and a fast response internal comparator to discharge the MOSFET Gate in the event of reverse polarity. This fast pull-down feature limits the amount and duration of reverse current flow if opposite polarity is sensed. The device design also meets CISPR25 Class 5 EMI specifications and automotive ISO7637 transient requirements with a suitable TVS diode.
