No idea, made my own.
Pic is a H bridge with discrete drivers and a pwm driver I scrunged up to test stuff.
Rise and fall times are on the region of 200-300ns.
Now I'll make the board that'll house the controller and the pwm switching so I can run AC stuff and modulate signals.

>voltage:
5-20V
>current:
It's limited by the PFETs I think. They handle 48A, while the NFETs handle 100+A . I guess it'll be limited by heating.
>control scheme
Only diagonal FETs are active at the same time, only one PWM signal is used. Total digital pins used will be 4. (ground, supply, pwm, multiplex)

Isolated inputs.
