Hi,
A continuation of the related question.
https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1181848/drv5011-phenomenon-in-which-an-abnormal-signal-is-seen-in-the-output-of-the-drv5011/4461624#4461624
A new chip (DRV5011) obtained from TI online was mounted on the motor, and a test was conducted to see if chattering was improved. As a result, chattering was observed even with the improved tip.
In addition, it seemed that there was not much change in the occurrence frequency and pulse width compared to the one before the improvement.
In the related question E2E, there was an answer that this chattering phenomenon was confirmed in the old silicon version and improved in the latest rod. Are there any factors? When I checked the surface of the DRV5011 package used in the test, the marking was 1AD. I bought chips at the TI store around February 2023.
Thanks,
Conor
