8.4.5.6 Control Coefficient

The DRV10983 continuously measures the motor current and uses this information to control the drive state of the motor when operating in closed loop mode. In applications where noise makes it difficult to control the commutation optimally, the CtrlCoef[1:0] can be used to attenuate the feedback used for closed loop control. The loop will be less reactive to the noise on the feedback and provide for a smoother output.
