MCT8316Z: MCt8316Z SPI interface current fbk question

Hi ,

Thanks for posting your question.

We are OOO this week, our response will be slow.

Regarding your question,  the Isense in MCT8316 is used for CBC. The FOC based products MCF8316C provides many variables through I2C access .

What is your End application ? Can you look into FOC based products?

Thanks and Best Regards

Our application does not have the capability to turn motor for self alignments and self calibration which is required by FOC. We need to use Hall based sensors to commutate. Current fbk is needed to provide a closed loop current inner loop where outer position loop demand can be a torque value. Also current fbk will be used to predict frictional loads as part of an optimization, adaptive control concepts. 

I realize this chip does nt provide direct pin for current feedback; does it have SPI based current reading capability?

Also SPI version and even Hardware version has limited dir control with commutation tables. This prevents device to perform in true 4 quadrant mode. Like to know if any future plans for these functionalities?

Hi,

Thanks for sharing the details. I will respond by end of this week.
