DRV8214EVM: Can stop Motor when reaching pulse threshold?

Part Number: DRV8214EVM

Tool/software:

Dear team,

Does EVM have capability to stop the output when reaching the counted pulse threshold?

I know the IC does not have this capability and just flag the nFault or CNT_DONE register. We also found the function it can reverse but could not find that function.

Best regards,
Yuto 

  • Hi Kitamura-san,

    The IC has the capability to stop output. Refer to the register RC_HIZ. It can Hi-Z the H-bridges when RC_CNT exceeds threshold. 

    Setting this register to 1b will solve the problem. Let me know if I misunderstood and you were referring to something else when you mentioned 'stop output'.

    Regards,
