[ DRV2605L-Q1 ] Immersion License for Combination Usage (DRV2605L-Q1 and DRV2700)

Hi,

Your app note (SLOA255) suggest to use DRV2605L-Q1 together with DRV2700.
In this case, the license from immersion is applicable for DRV2605L-Q1, and for DRV2700, it's not necessary.
Correct?


As my understanding, the discussion with Immersion is necessary for the device which have pattern generator and/or any functional block for haptics pattern generation.
On the other hand, the device only has driving circuit (no pattern generation related function) is not required the license.

Thank you for your support in advance.
Regards,
Ken

    Hey Kenichiro,

    The DRV2700 is merely amplifying the signal in this scenario, and is not involved in pattern generation as you described it. The DRV2700 may be used in many applications that require amplification and is not tied to Immersion or Immersion’s waveforms. The license on the DRV2605L covers the use of Immersion’s embedded waveforms, per the legal notice you provided that is from the DRV2605L datasheet. If you require additional legal guidance, please consult your attorney because TI cannot provide you with that guidance.

    Hi Micar,

    Thank you for your reply! It's good to know that you and I have generally same understanding.

    Actually, this is not the discussion I want to get in and let my customer and immersion discuss directly.

    Thanks,
    Ken
