PCM2906C: Suspend status.

Kengo.Y

Part Number: PCM2906C

Hi team,

Will the suspend status continue even if there is no power supply to VCCCI(10pin)?
In the other words, if there is only VBUS (3pin), will this mode continue?

It is designed with reference to Fig.36, and my customer are considering cutting off the power supply of VCCCI in the Suspend status.

Sincerely.
Kengo.

Hello Kengo,

I believe suspend will still hold. I don't have an EVM on hand at the moment to verify but I may be able to get one next week. Is the customer powering down to save power? When in suspend mode, there is a ~20mA reduction in system current already.

Regards,

Aaron Estrada

Hi Aaron,

Thank you for your reply.
I'll wait for your check by EVM.

He wants to reduce power consumption as much as possible.

Sincerely.
Kengo.

Hi Kengo,

I received the EVM today and was able to confirm that SUSPEND will still hold if VCC is not supplied. I appreciate your patience!
