Part Number:DRV8308EVM
DRV8303 is using in the DJ turntable, which care about noise and some special operating condition.
Our customer has three question about the DRV8308 GUI modification,
1. The customer testing with PWM MODE, setting SPEEDTH = 25%, MINSPD = 255, 70%DUTY to start up.
It took about 2.1sec. to enter the sine control mode, how could we set the mode to enter sine control when started vs waiting for 2.1 sec
2.When the motor is turning, and user need the function of using hand to scratch the disk with not enter the fault condition and stop turning.
The test result is the Scratch caused our DRV8308 entering the fault protection and stop.
I read the 0X2A, and try writing to 0, but it didn’t work, and the default reading is not 0X18 also.
How could I fix this?
3.DO we have the document about how to modify the Hall sensor location in BLDC to optimize the Performance and startup speed?
