Mosfet identification

JR Z3650 servo with some blown components two of which i think are dual channel Mosfets 1024 & 2024. The chip in lower right corner looks popped also, is that one a signal inverter?

I would guess its a bridge mosfet driver, maybe an MC4428 or similar? the 4428 includes an inverter on one side of the bridge

The PDF does not match the pin out by the look of the PCB. Also, most 1024/2014 dual mosfet devices are 6 pin rather than 8.

I think I found them, looks like Hitachi might make them too.
Now the chip in the lower right corner & hopefully the micro controller on the other side is ok.
