Texas Instruments also manufactures a chip that contains only the brains, as it were, of the smart diodes ->
LM74610-Q1 Zero IQ Reverse Polarity Protection Smart Diode Controller
The major benefits are
- You can use any N-channel MOSFET with it. I plan on using MOSFETs that have a maximum steady-state current of 195 A.
- As there is a charge pump onboard the chip, it has no need for either a dedicated voltage drain (ground) or a supply. Therefore, you can plug it into a circuit just like a normal diode.
The voltage drop of 0.07 V(rms) at conduction in a leg of a full rectifier is much more attractive than the 0.4 V(rms) of a Schottky diode, as is the "reverse polarity" behavior.
