LM74703-Q1/LM74704-Q1 Ideal Diode Controller

Texas Instruments LM74703-Q1/LM74704-Q1 Ideal Diode Controller operates in conjunction with an external N-channel MOSFET as an ideal diode rectifier for low-loss reverse polarity protection with a 20mV forward voltage drop. The wide supply input range of 3.2V to 65V allows control of popular DC bus voltages such as 12V, 24V, and 48V automotive battery systems. The 3.2V input voltage support is designed especially for severe cold crank requirements in automotive systems. The device can protect and withstand the loads from negative supply voltages down to -65V.
