  • DRV2624: Output impedance question

    TI Thinks Resolved
    Part Number: DRV2624 Hi All, May I have your help to explain the meaning of below 3 parameters? or there is a training video that can share with us? Looking forward to your reply. Thank you.

  • DRV2624: Question about DRV2624

    Part Number: DRV2624 Hello： My client is using DRV2624, The problem is that after F0 calibration, some machines will have long vibration + weak vibration after hard restart. Under normal circumstances, the machine will not vibrate after manual calibration…

  • DRV2624: Differential output waveform format

    TI Thinks Resolved
    Part Number: DRV2624 Other Parts Discussed in Thread: DRV2625 Hi Team, My customer asked us if we have haptic solution that used square wave output + filter to get sinewave output. About our DRV2624/DRV2625, our differential voltage output are sinewave…

  • RE: DRV2624: Function of calibrating to find the resonant point

    Resolved
    Hello Shotaro-san Among the tools we provide we have the accelerometer tool: www.ti.com/.../DRV-ACC16-EVM But is there no datasheet you have for this actuator? usually actuators come with resonant frequency provided in their datasheet. ERMS do not have…

  • DRV2624: some of the watches vibration issue

    TI Thinks Resolved
    Part Number: DRV2624 Hi team, After DRV2624YFFR motor drive is calibrated at F0, some watches will vibrate after hard restart of the watch. From the quantitative waveform, I2C has no communication, and the chip is not fully up, the motor vibrates by…

  • DRV2624: frequency is changing if the voltage into motor is low

    Part Number: DRV2624 Hello TI experts, My customer made their product using DRV2624 and LRA motor, and they found a problem. first they tested as the diagram below. the problem is, when the voltage into the motor is 2.5Vrms, motor works normally. but…

  • Compiler/DRV2624: DRV2624

    TI Thinks Resolved

  • DRV2624: How to determine Diagnostic failure when no load is connected to OUT+ and OUT-

    Resolved
    Part Number: DRV2624 Hi, Based on the datasheet (8.3.2.6 Actuator Diagnostics), the DRV2624 driver could also detect the absence of a load, how could we determine the diagnostic or autocalibration routines are failing because of this? , none of the four…
