I need your advice on high power device selection.
I'm working with a similar application to this schematic, with the descriptions being in this forum. Without reading through the dozens of pages (and several bad Oprah jokes that I don't get): it's a motor driver circuit for an electric vehicle.
Think 500A, 144V driven with PWM at 16kHz. Parallel NMOS looks like the best solution, though I'm open to suggestions for monster parts that would be in the same price range and handle the full load...
With this kind of power, I'm thinking it's very important to have minimum losses (the original gate driver is described as an "Ultrafast MOSFET Driver", and the NMOS is rated at 11 milli ohms). Price is a consideration, but should be compared to the losses adding up with daily driving use over years and taking range into consideration.
The driver in the schematic is EOL from what I can tell, so I need a recommendation on the driver as well.
In summary: I need selection help for MOSFET, flyback diodes and gate driver IC for this application.
