Brushless DC Motor Driver IC? (X post from r/Arduino and r/RadioControl)

What I'm looking for is a single driver chip. Something like the L298 but can handle a BLDC with ~10A (per phase) continuous draw with 4S voltage input. I want both forward/reverse. Control can be via PPM (servo signals) or PWM, it doesn't matter much to me.

I know I can use a off the shelf ESC but I want to integrate this on to my own PCB which will contain other parts (ie. accelerometer, etc), so I would need to get the driver chip itself.

I have been looking for this for a while, and the closest I've found was the DRV8332 datasheet here, PDF but that still doesn't give me enough amps per phase continuously (this one gives 8A per phase with 13A peak). The DRV8332 does what i want except it can't do 10A+ continuous per phase.

I am fully aware I can make a circuit/driver using 3xH-bridges and a bunch of other things, but I really want an all in one driver IC.

Cost or package type isn't really an issue.
