Do you have suggestions about which h-bridge should I use to drive a DC motor 27v 3A using Arduino/PWM?
I did som research and I could only found this 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.
