Expert 3040 points
Part Number: DRV8308

Hi team, my customer is want to konw required min REST period, please let me know.

This seems not described at datasheet, and customer experienced that  writing data is invalidated ("0"), when reading at the following procedure of #4. 

#1 Turn on the motor driver

#2 After REST = high for 800ms, set RESET pin to low, and write the necessary data by SPI

#3 Stop after motor one time rotation

#4 After REST = high for 10 ms, set RESET to low and read the data, but written data is invalidaed, ="0". 

Please let me know. 

Best Regards, ny
