DRV8301-69M-KIT: Current sense amplifier

Part Number: DRV8301-69M-KIT
Other Parts Discussed in Thread: DRV8301, , MOTORWARE

Hello TI,

We are working on DRV8301-69M-KIT with 28069F MCU. This EVM board support three external current sensing amplifier and DRV8301 have two current sense amplifier in-built. 

All motorware projects are using only the external current sensing amplifier. Can we bypass the external sensing and using the in-built current sensing from DRV8301.

Thanks

    Yes, you can. But you need to change the ADC configuration and reading functions in hal.c and hal.h, and also need to change the USER_ADC_FULL_SCALE_CURRENT_A in user.h according to the gain of the DRV8301.

    And you have to set the USER_NUM_CURRENT_SENSORS as below in user.h 

    #define USER_NUM_CURRENT_SENSORS            (2)
