hey i'm building a satellite tracker for a project. We were using an LM18298 to drive a stepper motor, but the motor we had ended up bein too weak for the gear ratio that we are using.
So now we are usin a DC motor.Can i use a PWM on the enable pin of one of the channels? ie direction will be set by the two input pins and the enable used pin to drive
please help, this is a last minute change to our project
thanks
edit--
as well the data sheet says the typical commutator frequency is 25kHz.....is this the optimum PWM freq?
