    Rajat,

    The maximum PWM frequency is related to the external switch FET's Qg and charge pump current capability. The equation is on data sheet page 49. If the input signal INx is higher than that limit, you have to reduce it.
    Yes. The PWM frequency is supplying to motor by turning on or off the external switching FETs.
