DRV8833: Large current spike at startup

Part Number: DRV8833

Hi there,

My customer observed a large current spike at motor startup. Please refer to the waveform below. (Measured at AOUT1)

Please also find the schematic attached.

Could you please give us some hint to figure out the cause?

Thanks!

Best regards,

Roy Hsu
