    Hello guys. I would like to connect two L298 in parallel to drive a stepper motor which needs 2.2 Amps.
    Is it good the schematic i posted? I want to use 1N5822 diodes. Should i also use some ceramic capacitors? Thanks. schema1.png

    L298 chips are out dated chips for stepper driving. A dedicated stepper driver chip is a better option.

    A dedicated driver chip will have a built in PWM to control the current to the motor which is important. Stepper motors are very tolerable to voltage( should actually be ran at 10 - 20 times the name plate voltage of motor) But very intolerable to over current.

    A dedicated driver will also generate the step sequence for the motor including micro stepping. Micro stepping makes the motor operate much smoother.

    And a name for dedicated driver chip please? L298 is very easy to implement. Someone suggested L6208 but its very ambigous how to interface it with a microcontroller. I want a simple solution. Thanks

    Good first post on the site. Why do this instead of helping?
