DRV2604L: Abnormal noise

ACGUY

Part Number: DRV2604L

Hello E2E,

Our customer is evaluating the DRV2604L with LRA motor.
The LRA motor has abnormal noise at operating.
Can the abnormal noise be solved by setting the register?

Hello ACGUY,

Can you provide an oscilloscope capture of the output waveform when this abnormal noise occurs? Also, is this using the EVM motor or one the customer has?

Thank you,

Justin Beigel

Hi Jjustin,

Thank you for reply. The motor was prepared by the customer. I will request a waveform to customer.

Hello ACGUY,

If possible, can you also acquire their register settings incase we need them to debug this issue.

Hello ACGUY,

I haven't heard from you in a while so I am closing this thread. Feel free to respond here or open up another thread if you get the waveform and register settings from the customer or have any other questions.

Best Regards,
