3 Description 

The LM74700-Q1 is an automotive AEC Q100 qualified ideal diode controller which operates in conjunction with an external N-channel MOSFET as an ideal diode rectifier for low loss reverse polarity protection with a 20-mV forward voltage drop. The wide supply input range of 3.2 V to 65 V allows control of many popular DC bus voltages such as 12-V,24-V and 48-V automotive battery systems. The 3.2-V input voltage support is particularly well suited for severe cold crank requirements in automotivesystems. The device can withstand and protect the loads from negative supply voltages down to-65 V.

The device controls the GATE of the MOSFET to regulate the forward voltage drop at 20-mV. The regulation scheme enables graceful turn off of the MOSFET during a reverse current event and ensures zero DC reverse current flow. Fast response(<0.75 us) to Reverse Current Blocking makes the devicesuitable for systems with output voltage holdup requirements during ISO7637 pulse testing as well as power fail and input micro-short conditions.

The LM74700-Q1 controller provides a charge pump gate drive for an external N-channel MOSFET. The high voltage rating of LM74700-Q1 helps to simplify the system designs for automotive ISO7637 protection. With the enable pin low, the controller is off and draws approximately 1-uA of current.
