Dear TI Support Team,
I am developing with DRV10983.
I succeeded in driving a motor with my new pcb board. ISD, and IPD are all enabled and Motor speed is controlled by I2C Speed command.
However, after several days of testing, there was a phenomenon that the motor did not start envn when I power again the target board.
At this time, even IPD did not work (there was no IPD sound). But in this status, the fault code = 0x00 and MotorSpeed (0x11: 0x12) had some value.
In this case, if I move the motor slightly with my hand, the IPD operation sounds are heard and the motor starts rotating normally.
It was a symptom that did not appear at first, but it continues to occur in many target boards.
The circuit is almost same as the DRV10932 datasheet and has been in normal operation until this occurs and is occurring over time.
Is there any solution to solve this problem?
Best regards,
Peter
