DRV2605L: LRA Frequency Range

Part Number: DRV2605L

Hi Team,

The LRA Frequency Range specification of 125 - 300Hz is a design guarantee.

What will happen if I deviate from this?

Best Regards,

Kenji

  • Hi Kenji,

    this frequency range is specified for closed loop operation. if you use an LRA with a resonant frequency that is out of specification then our driver will not be able to track it. You wont be able to use the auto braking feature, and closed loop performance in general will be poor (weak, sporadic vibration)

    However you can still use an out of specification LRA for Open loop operation.

    Regards,
