Part Number: DRV2624

Hello TI experts,

My customer considers DRV2624 for their new product. Could you review the schematic?

- MOTOR_PWR is 3.0V.

- They will use DC motor. should we add additional schematic for back EMF?

Best regards,

Chase

    Hi ,

    Apologies for the delay our haptics expert, Arthur, is out of office and has limited access to E2E. Please wait patiently for his response as it will be delayed.

    Hi Chase, 

    I do not see any issue with the schematic. 

    Will the customer be using the TRIG/INT pin as interrupt or as  external waveform trigger?

    If the customer is using this pin as an interrupt then the schematic is OK. If the customer is using it as external trigger then I recommend to remove R114.

    There is no need to have an additional schematic for the Bck EMF.  DRV2624 can track the back EMF with no additional circuitry.

    Regards,
    Arthur
