DRV2605: Setting for ERM by external PWM input

Part Number:DRV2605

Hi,

Our customer is considering to drive ERM by external PWM input.

Please tell me which registers must be set.

I think that the following procedure is necessary to make it an external PWM.

1. Power on

2. Turn EN to high

3. STANDBY bit = 0

     At this point the device status is active

4. MODE[2:0] = 3

5. N_PWM_ANALOG = 1

   When PWM is input at this point, the motor turns.

  I think that they can check whether the motor moves at this point excepting control.

  Is it correct?

Next step, I want to know the registers necessary for controlling ERM.

Are there any registers that must be changed from the default?

Best regards,

Tomoaki Yoshida
