As far as the PWN inputs, do I just need to supply it a continuous PWM at specific frequency with duty cycle that corresponds to how fast I need the motor to spin? I assume the DRV8303 takes in the continuous PWM, and has the control logic to determine the appropriate timing of the switching for 3-phase BLDC? Can all 6 PWM inputs be driven with one PWM output from a MCU, if we independently buffer the signal for each 6 inputs?
Also, since the DRV8303 does have inputs for the sensors on the motor, what kind of effect would it have on the operation of the motor when sensorless?
What would you recommend if we decide to use the sensors?
Thanks
