DRV8834: About actual waveform at over current protection(OCP)

Part Number: DRV8834

Hi Team,

We understand that the behavior of OCP and H bridges is the following chart.

Is my understanding correct?

And, our customer would like to know the actual waveform at over current protection(OCP).

Could you please let us know if you have any actual waveform?

(Our customer’s condition(VIN, IOUT etc.) is TBD so thiere is no specific test conditions.)

Regards,

Hi Kanemaru-san,

Your understanding is correct.
We will look if we have any existing OCP waveforms. If not, we can create one, please just allow us sometime. Thank you.

Hi Kanemaru-san,
We do not have an existing OCP waveform. Please allow couple of days to provide you one. Thanks.

Hi Kanemaru-san,

Please see OCP waveform as requested.

Channel1 (Yellow) = nFAULT

Channel2 (Teal) = I_OUT

Channel4 (Green) = V_OUT

Thank you.
