BOOSTXL-DRV8304H: Fault status

Part Number: BOOSTXL-DRV8304H
Other Parts Discussed in Thread: DRV8304, MSP430F5529

Hi Team,

Customer is having issue with our device. Below is the inquiry.

"

I have recently purchased the Motor drive evaluation board(BOOSTXL DRV8304)..There are some software issues while connecting to the motor. I wanted to clarify whether it is a software problem or hardware problems.

I have merge the launchpad and DRV8304 evaluation board. Now i have uploaded the example code Trapesoidal sensored code and after that I have opened the BOOST XL software.

It shows that power supply is low, but i have checked the main supply which gives 24V as main supply

"

Regards,

Maynard

    Hi Maynard,

    Do you know if the customer is using the MSP430F5529 LaunchPad development kit? The software is written specifically for that MCU, so if they tried to use a different MCU then the code wouldn't be compatible. If they are using the correct LaunchPad, then could you ask the customer to probe the VSENVM header pin? this is J5 pin 3

    VSENVM pin is circled in blue below:

    I want to make sure that there is power going to that pin, since that would be what the software would use to tell if the main power supply has a high enough voltage on it. The voltage at that pin must be greater than around 0.419V for the controller to think that the power supply voltage is high enough. with a supply of 24V I would expect to see about 2V at the VSENVM pin if everything is working as intended. If the customer sees the expected voltage at that pin then it may be good to double check to make sure they didn't accidentally plug in the launchpad into the header the wrong direction. 

    Regards,

    Hi Anthony,

    Below is the response of the customer.

    "I have a small doubt.. I want to check the VSEN probe without launchpad board attachment or with launchpad board atatchment?"

    Hi Maynard,

    If the customer can check VSEN probe while the launchpad board is attached that would be best, but if not than it would be fine to check it when it is not attached.

    HI Anthony,

    I just received response from our customer.

    According to them, when the launchpad is not attached they are getting 2.03V in the VSEN probe but while attaching the launchpad they are not getting 2 V in that probe. 

    Customer have ordered new launchpad board and they will check once it is arrived. If there is any problem they will informed us.

    Regards,

    Maynard

    Hi Maynard,

    Sounds good. When they attach the launchpad does the VSEN drop to 0V? One possibility is if they accidentally misaligned the BOOST-XL on the Launchpad by placing the BOOST-XL one row to the right then that would result in the ground of the MSP430 being connected to the VSEN of the BOOST-XL. The image below shows the correct way to connect the BOOST-XL to the Launchpad outlined in black, and a possible misaligned connection outlined in blue. 

    Regards,
