    IC manufacturers have parts whose datasheets are not available to the everyone and are not on the web. It's also a possibility that it's an knockoff from China or something, and the datasheet doesn't exist.

    It is in a 3000 watt 12vdc inverter which blew all its mosfets, with shorted Drain to Gates, and many subminiature gate resistors.

    A single PWM KA3525A is sending the signal to the RX3152, two on the primary board and two on the synced board.

    So I think these RX3152 are the drivers for the mosfets.

    What is the probability that any of these are destroyed? Those look on the exterior fine.

    well it is unrepairable, so I going to junk it and recycle the aluminum case and heat sinks.
    I just replaced all the Mosfets and all the gate resistors and it burned them all up and let out a solitary beep.

    Beyond my ability. IMO, inverters over a threshold of 1500 watts are too expensive for what is in them. And they are not robust enough to deal with faults overloads. Better using a generator.
