Dear community.

Our customer has question below.

 

the following power supply configuration, over-current flows in the SoC of the line before and after the oscillation of the GDC, SoC power supply voltage is reduced in its influence.

Events subsequent power resulting in OFF has occurred.

Waveform of when an event occurs Please refer to the attachment sheet.

For this reason would you please advice.

 

- ARM / SoC after the power is turned on, the reason for that the movement and the mechanism by which the over-

  current is generated before and after the GDC is to start the oscillation is the correct design.

 

 

- Workaround at GDC side order, this event will not happen.

 

please refer attachment figure.

 

Thanks,

Best.
