DRV2624: Output impedance question

Evan Wang
Genius 9690 points
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.

    Hi Chia,

    The values ZO(SD) and ZO(STBY) are the output impedance of the DRV2624 in standby mode ( the device is in standby when powered on, NRST=1, and not playing a waveform) or when the device is is shutdown mode (NRST = 0)

    when the device is in Standby or shutdown the outputs can be modeled as this:

    The value ZLOAD(th) is the load (LRA or ERM) impedance that will cause the Over-Current Protection (OCP) to be tripped. This means that the below condition will cause the device to trip OCP and the device will enter standby mode

    Regards,
