Hi,
I'm planning to use the DRV8432 for controlling a DC motor with a maximum current of 12A. So I need to use he DRV8432 in pararell mode. But, after readind the post 'DRV8432DKD cycle-by-cycle current limit' (http://e2e.ti.com/support/applications/motor_drivers/f/38/t/133322.aspx?pi239031349=2), I'm quite confused. Can I control the motor with a PWM signal in PWM_A and GND in PWM_B? Because,in principle,that's theway to do it. But, if I have understood correctly what it is said in the post, controlling like that causes that the DRV8432 is stuck when the output hits CBC limit.
In pararell mode I can't use the OC latched mode and I need to have control over the maximum current. So, is the only way to control the motor to connect a PWM signal to one input and the complementary PWM signal to the other input? Can I have anyproblem ifI do it thisway?
That is, ifI want to usethe parallel mode and to have the cycle-by-cycle current limit working correctly, how have I to manage the inputs?
Thanks,
Fernando.
