DRV2510-Q1: Solution and design check

Kai Lai

Part Number: DRV2510-Q1
Other Parts Discussed in Thread: DRV2605L-Q1, TPA3110D2-Q1

Hi Team,

My customer now is designing a Automotive Infotainment system, need the LRA/Haptic *4 in their design.

The LRA(or Haptic ?) datasheet as below.

And I also get the current solution datasheet (competitor) from customer, if you need or interesting it, please send me a mail, I will share you off line.

Does TI have suitable solution can drive above device ? Please advise.

DRV2510-Q1 is fine ?

Thanks!

    Hi Kai,

    I sent you an email regarding the competitor D/S. For automotive 

    Does the customer plan to use a single IC to drive 2x LRA in parallel, or use 2 ICs?

    What is voltage the customer wants to drive to the actuator, the datasheet give 35Vp-p at the maximum, is this necessary?

    Our automotive haptic drivers are DRV2510Q1, DRV2511Q1, and DRV2605L-Q1. If the customer can accept a Vp-p of 10V then DRV2605L-Q1 may be acceptable. This part has the benefit of auto resonance tracking.

    Otherwise DRV2510-Q1 is likely the best option for haptic drivers

    We may also consider a stereo audio amplifier like TPA3110D2-Q1 as a single chip solution to drive 2x LRAs

    Regards,

    Hi Arthur,

    Thanks for your feedback. I have sent the competitor information for you by mail.

    After check, there will have 4 LRA, and customer plan to use 4 Haptic driver for each.

    Their current design with the competitor driver will out put 10.2V half wave, then custom will combine two half wave to a full Sine wave(I don't know how they combine its?) then output a 20.4V Full wave to drive the LRA. The wave as below capture.

    So do you think DRV2510-Q1 is a good solution can replace competitor here?

    Hi Kai,

    the 10.2V waveforms are the P/N outputs from the differential amplifier.

    I have sent you an email regarding a proposed solution in this case
