    Hi,

    Do you have suggestions about which h-bridge should I use to drive a DC motor 27v 3A using Arduino/PWM?

    I did some research, and I could only found these two (affordable price):

    l298:
    This guy is very famous, but it supports only 2A max current. Moreover, I found I can use it in a parallel configuration to drive only one motor using a higher current, but I could not find anything about how to implement this configuration, and I also found it has a big voltage drop between vcc and its motor output jack, so it is not a reliable alternative.

    Vnh2sp30:
    This guy can support 30a max current, but only 16v max voltage.

    Thank you

    You can go to Digikey.com, search on "H Bridge", and set filter to
    find parts bearing your specs. Then look at feature sets of the
    individual parts found.

    Regards, Dana.
