When pressing button 5 seconds, pmic goes off and inmediately goes on again
The correct behaviour should be to be off until new pressing its performed
Please see attached PDF Schematic Docs and help me
I need to start massive production just now! (50.000 pcs) near to $50 /pcb

After 5sec pressing button, PMIC_ON_REQ goes down but it goes up again after 18ms

Hi Nacho,
Problem seems to be the configuration of the RESTARTEN bit (Bit 0) of the Power control register (PWRCTL), if this bit is set to “1”, the PF3001 restarts automatically after a power off event generated by the PWRON (held low for 4 seconds or longer) when PWR_CFG bit = 1. Make sure this bit is set to “0”.
Have a great day,
Jose

Dear Jose
I´ve performed as you commented:
It still fails but, the problem its not the PMIC, its the IMX6!
Because pmic goes off inmediately whrn PWRON its low (tested):
Please help us with this problem we have prodiuction stopped
If we dont fond the solution i PREPARED A VERSION that bypass the soc onoff stuffand perform the onoff function directly with the BIOS PIC MCU

Hello,
Hope the following helps.

Perhaps it is needed to have the SNVS voltage applied (say, from coin cell)
to avoid the issue.
