Care to elaborate? Don’t name names if you don’t want, but what did you hear? As I recall reading there are about 18 FETs form ON semi form what I remember, and they were lower on resistance (less voltage drop and heat), and are just released. That may only give you 3 fets per phase conducting at a time, but they are better fets. I remember the days when IRF was dropping the Rds on their fets in half almost every year. And that was back when the best Rds you could get was 28 milliohms.
