MCT8329A: Reading the motor voltage via the DAC

Part Number: MCT8329A

Tool/software:

Hello 

Is it possible to read the voltage applied to the motor using the DACOUT line on the MCT8329A?

Thanks

    Hi Ron,

    The DACOUT can be set to output the values contained outlined in Table 7-57 Algorithm Variables in the MCT8329A datasheet.

    So while the voltage applied cannot be explicitly output by DACOUT, the CURRENT_DUTY can which can be used, if the voltage input to VM is known, to determine the applied motor voltage.

    Regards,

    Joshua
