Other Parts Discussed in Thread: DRV10975

Hello Team,

When using DRV10975 at Override bit = 0, motor speed could be controlled with analog input to the SPEED pin. In this condition, would the register setting at Address 0x00/0x01 "SpeedCtrl1/2" affect the motor speed or is the setting ignored ?

Hi Kawai-san,

In DRV10975 Override bit = 0 mode: SpeedCtrl1/2 information would stay what were set. It won't affect motor speed and SpeedCtr1/2 setting won't be changed while SPEED pin voltage change.

Hello Janet-san,

Thank you for your answer.
Please allow me to confirm that even when the user changes SpeedCtrl1/2 through I2C/SMBus, would there be no affect to the motor speed ?
