DRV8363-Q1EVM: Pinout question – HALL_C signal

Part Number: DRV8363-Q1EVM
Other Parts Discussed in Thread: LP-MSPM0G3519, , DRV8363, DRV8363-Q1, LAUNCHXL-F280049C

Tool/software:

Hello,

I am looking at the compatibility of the DRV8363-Q1EVM with the LP-MSPM0G3519 EVM. I have an issue with the HALL_C signal. How should one read the below schematic? Is this signal available both from the J8.7 and J9.17 pins? Why is it crossed out for J9.17? Actually, it would be good to have HALL_C available for J9.17 for the compatibility with the LP-MSPM0G3519 EVM because it is an analog pin when J8.7 is not.


Best regards,
François.

    Hi,

    I have pursued my analysis using slvud90 page 14 and slau947 page 10 as reference schematics, and came up with the below. Please confirm if my analysis is correct, especially with the connector pins that I think are incompatible between both boards.

    Hey Francois,

    The DRV8363-Q1 EVM was built for compatibility with LAUNCHXL-F280049C. In one of our initial revisions we had challenge running HALL C to J9.17.

    The Hall signal would not toggle which affected Hall based commutation. Therefore, We moved it to a different location (which we knew worked based on previous EVMs).

    I am looping in MSP team to comment on any potential challenges with this arrangement.

    Best,

    Akshay

    Hi François, 

    If there remained the resistor on EVM (R6/R10), then it can be worked with LP-MSPM0G3519, as user can manually remove R6 and add R10 in the EVM board.

    Hall signal is digital signal, so it can be used with PA10/PA11/PA12.

    PB10 doesn't works for ADC function, there requires additional wire connected externally to the pin supports ADC function and not used.

    B.R.

    Hi Akshay and Sal,

    Thank you. I was mistaken in the nature of the Hall signal. So, only ISENC/PB10 should be wired separately, plus R6/R10 taken care of.


    Best regards,
    François.
