  • DRV2605L-Q1: some questions

    TI Thinks Resolved
    Part Number: DRV2605L-Q1 Hi team, Could you kindly tell me what is the difference between below 123 waveforms? Thanks! Appreciate! BR Jiawei

  • DRV2605L: [DRV2605L] About the Waveform Library

    TI Thinks Resolved
    Part Number: DRV2605L Other Parts Discussed in Thread: DRV2605 When I saw the datasheet about Waveform sequencer, it described that when I set the bit 7 (Wait bit) for Waveform Sequencer, WAV_FRM_SEQ[6:0] bit will be interpreted as a wait time. It means…

  • RE: DRV2605L-Q1: Several questions about DRV2605L-Q1

    Hi Johnson, in RTP mode(and all other modes) the LRA will be driven at the frequency that is found during the auto calibration routine. and then using the RTP_INPUT[7:0] register field you can control the 'envelope' of the waveform. We don't have a tool…

  • DRV2605L: LRA rated voltage setting

    Resolved
    Part Number: DRV2605L Hi Team, We would like to control LRA with open loop mode, the rated voltage of the LRA is 1.5Vrms. I would like to know how to setting parameter to meet rated voltage? Thanks, Best regards, Jason

  • RE: DRV2605: DRV2605 as an alternate to the DRV2605L

    Hi Jerry, there are some differences in the register maps for these devices. the registers related to the LRA calibration should be the same between devices (0x16-0x1A) however there are some differences. your firmware may be writing to some incorrect…

  • RE: DRV2605L: Rated voltage

    Thank you for your kindly response. I just want to double check the process to set LRA with DRV2605L. Before starting to drive LRA for my research project, I need to do auto-calibration. Then, do I need to do it again whenever I start driving motor? …

  • RE: DRV2605L-Q1: Whether the chip can be endowed with PWM through I2C without PIN4 input PWM?

    Tommy, What frequency are you driving in PWM mode? The max is 250kHz You can set the open loop period in register 0x20 using this formula: LRA open-loop period (µs) = OL_LRA_PERIOD[6:0] × 98.46 µs 0x22 reports the measured resonance period…

  • RE: DRV2605L-Q1: Does TI have a tool to make the waveforms which will be used in RTP mode?

    Resolved
    Hi Johnson, we do not have a tool for generating the waveforms for RTP mode. the waveforms will need to be generated manually. You should create a sequence of writes that contain a amplitude values written to RTP_INPUT[7:0] register 0x02, and delays for…
