PF3000 1V8 IO Voltage

Hello Community


Id like to use 1.8V IO voltage throughout my entire system, including the connection between PF3000/MX7.

To achieve this, supplying 1.8V to the PF3000's VDDIO pin is necessary.
However, im not quite sure if i can take the 1V8 supply from the PF3000 itself or if an external regulator is needed.


VLDO1 is set to 1V8, so is SW2. But i guess these are both disabled if the PMIC was set to standby? So, as a result, the system could not be woken up by the MX7 anymore?
