Part Number: DRV8718-Q1
Other Parts Discussed in Thread: DRV8718S-Q1EVM

Tool/software:

Hi team,

My customer is testing DRV8718S-Q1EVM and met below questions, could you please help share some comments? Thanks.

1. (No Fault) The customer connect the motor at HB1 and HB2 and found that the status of the VDS_H1, VDS_L1, VDS_H2, VDS_L2 were incorrect and not the same as defined in the document as follows.

2.(Open Load)No motor connected at HB5 and HB6, the output is open, the status of the VDS_H1, VDS_L1, VDS_H2, VDS_L2 are also incorrect and not the same as the definition given in the document 

May I know what to do to achieve the output consistent with the truth table document?

Regards,

Ivy

  • Hi Ivy,

    Who is the customer and what is the application?

    I am assuming they are using the EVM. Can they check once the voltages on the SHx?

    Can they also check the register map page to see if it matches the GUI page?

    Is the register map updating regularly?

    Best,

    Keerthi
