PWM for DRV8432 in parallel mode
I am planning to use the DRV8432 in parallel mode to driver a single motor. Were can I find graphic examples of
the PWM control waveforms needed - show if there is any special timing delay or phase relationships required.
I have not been able to find anything on the TI website or just googling.
Figure 9 in the datasheet shows a schematic for the hardware hookup.
For open loop control of a brushed DC motor, you just PWM one input and connect the other input to GND. To switch directions, flip the inputs. For closed loop current control, please see the document attached.

Thanks for the reply, but I don't see an attachment. Could you please try again.
My application is for a closed loop brushless DC motor.
