I am using a dsPIC33 to generate PWM signals to the DRV8402 and I want to make sure the DRV8402 is the right product that I should use to drive brushed dc motors. Pretty much what I am going to do is have the PWM1H and PWM1L lines go to inputs A and B of the DRV8402 and from what I have read inthe forums and the datasheet all I have to do is to generate a PWM for one input and disable the other input and that will drive a certian direction and vice versa. This should work in that way if the mode is set to full bridge. Let me know if I am approaching this the worng way, beacuse this is the first time I am using a full bridge and Motor control. To make it more clearer:
PWM A - controls outputs A and B with output A being V+ and B being V-. PWM B would be at ground in this direction.
PWM B - control outputs A and B with output B being V+ and A being V-. PWM A would be ground in this state.
I hope someone from TI can shed me some more light to this chip. Thanks
