DRV8662 Phase Delay

Other Parts Discussed in Thread: DRV8662

On behalf of Jacek:

I checked data sheet which you sent to me and it is very helpful, but I did not found information about switching time of DRV8662 drivers.


There is only information that start up time is around 1.5ms. I understand that start up time is a time from the moment when EN input is set to the moment when driver outputs have set values adequate to state of IN+ and IN- inputs. Am I correct?
 
Information which I need is what is time delay between IN+ and IN- inputs and driver outputs? Can you help me with obtaining that information?

 

  • Jacek,

    The delay of the DRV8662 will vary with frequency, but should be acceptable for most haptics and audio applications.  See the results below.

    Frequency Delay
    150 Hz 137 us
    500 Hz 76 us
    1 kHz 51 us

    Measurements were made with 200nF load at 50Vpp output and a 1.8V input.

    150Hz

     

    500Hz

     

    1kHz


    Let me know if you have any questions.

    Thanks,
    Brian
