Original question:

DRV8308: DRV8308

DRV8308: DRV8308

Part Number: DRV8308

Hello,

We are trying to use the drv8308 with closed loop operation. After a few days of testing we were able to get the drive to work with different voltage and motors to simulate manufacture variance. Now we need to be able to determine how 'loaded' is the system so we can report that our product is not within the predefined production tolerance.

It is possible to read the resultant gain when working with Clock Frequency Mode trough SPI? If not, what is the alternative? Or it is not possible?

Thanks

    Hi Jonathan,

    It is not possible to read the resultant gain. External information is available to be monitored such as speed at the FGOUT, current by monitoring the voltage across the sense resistor, and phase voltage.
