Hi guys I am designing a circuit which will control a dc motor. In this circuit I don't need linear speed control, I intend to use the full speed or nothing (no pwm needed). The dc motor is 4A for 24V, and I need to control the direction of rotation. This circuit currently operates with relays, but I would like to use a more compact approach, and I was thinking about using one of those modules which already have internal drive and mosfets. I found some of these ICs, but most of them don't fit well with my needs (24V x 4A). IR3220 is one example of such device. Do you have any tips about what IC could I use?
