nRF5340 - VDD Power Supply

[Gabriele]

HI,

I want to power the system using a external regulated 5V source.
Then nRF5340 must be used in High Voltage Mode.
When operating in High Voltage Mode, the nRF5340 is powered through the VDDH pin.
As soon as I short VDDH to my 5V source, the VDD pin turns as an output, and can be used to supply external circuitry.

In such condition:

How is the VDD voltage ?
What is the maximum current one can draw out of VDD pin ?

Best Regards,

Gabriele

How is the VDD voltage ?

 The VDD output voltage is set in register VREGHVOUT, when EXTSUPPLY is enabled.

What is the maximum current one can draw out of VDD pin ?

This value is TBD in the final product revision.

BR,
