Medium power full bridge driver

  1. I can't seem to find a medium power(about 180W) full bridge driver to drive
    a [email protected] BDC motor.

    Most I see are rated for around 3A or so cts.

    What do I need to do? Can I parallel these things(and is it even worth it)
    or am I just not looking in the right place? I don't need all the bells and
    whistles I see on some of these drivers but just something that I can drive
    from a uC using PWM for variable speed control(and the ability to reverse
    direction hence the full bridge).

    APEX semiconductor has them.

    Don't come crying to me when you see the price tag -- remember that all
    you had to do was slap it on the board.

    Do you need to implement control loops in software?
    "Applied Control Theory for Embedded Systems" gives you just what it says.

  3. Perhaps use a HIP4081 to drive an external MOSFET bridge?
    I think they're good at 12V (and up to 80V). The high-side
    drive capability means you don't need P-FETs, just 4 N-FETs.
