DRV2605: Fixed LRM Frequency

Part Number: DRV2605

Hello

I have an application where I'd like to fix the LRM frequency at ~170Hz - no auto resonance desired.

Is this achievable by doing the following?

  • Set LRA_OPEN_LOOP bit to 1 in register 0x1D
  • Set N_ERM_LRA bit to 1 in register 0x1A
  • Set DRIVE_TIME[4:0] to 24 in register 0x1B

Thanks!
