VDD and VDD_GPIO in PSM mode

[sssergsss]

Hello,

We are planning on running the nRF9160 with two supplies.  VDD_GPIO=1.8V and VDD=3.8V to get the best cell performance.

 

Can you tell me if I can turn off VDD_GPIO in sleep mode (PSM) or do I have to keep both supplies on at all times.

 Thanks 

Sergio

Hi,

 

Both needs to be supplied during normal operation, including sleep modes.

 

Kind regards,
