DRV8243-Q1: any connection between the logic pins and Vm ?

Expert 6385 points
Part Number: DRV8243-Q1

Dear team,

Would you be able to help me answering the following question regarding DRV824xS-Q1 (it would also apply to the H version)

  1. is there any risk in driving the SPI, nSLEEP, and other logic pins while VM is off (=0V) ?
  2. is there any connection between these pins and VM which might lead to a significant current leakage ?

Thanks a lot!

Best regards,

PA
