7002 power consumption

[allenyang]

I'm using custom board of nrf5340 with nrf7002.

Use helloworld sample and have set "config serial=n" and "config device pm =y".

The current is 90 ma when I don't do anything in the code, so I must initialize wifi interface to let the current be much lower.

There are two situations what I encounter.

1. The current is 1 ma when I use api, "interface down", to shutdown nrf7002.

2. The current is 0.5 ma when modify hardware to let the line of iovdd of nrf7002 disconnect.

The current difference of two situations is 0.5 ma, what causes the difference of current? How can I further reduce the current?

I'm using nrf5340(host ic) and nrf7002(wifi ic), but it's custom board designed by our hardware engineer. I'm wondering there are some problems causing the high current.

I can upload the schematic once you can identify the issues.

Allen

Have you done Schematic and Gerber  review before?
