Other Parts Discussed in Thread: INA240
I am selecting the current sensor for a FOC of SMPM.
The PWM frequency is 32kHz. DClink voltage 48V. The current is sampled each 32.25 uS. The output frequency up to 500Hz.
I am evaluating the TMCS1101.
In FOC the sampling instant must be accurate and sit in the middle of the two commutation to assure precision.
I am wondering if this chip, which update its output each 4us, can impact on the current reading introducing subharmonics or some other effects.
Which is your opinion?
