Dear All
How can we turn off the PMIC (Invoking the power off secuence and reset asserting, FROM SW ?
For turning it on we have a PIC microcontroller that turns on the PMIC by pullling down the SOC ONOFF pin through an open drain nand gate
I can connect a GPIO from SoC to PIC to indicate that turnoff can be performed but i prefer to turn off the pmic from SoC
Pic detects long pressings on a remote button that shorts to ground the externally pulled up 40v line
King Regards
Hi,
The PF3001 enters the Off mode after a turn-off event, turn off events can be achieved using the PWRON pin and PWRONRSTEN bit.
PF3001 can be turned OFF by setting PWRONRSTEN bit = 1 and keeping PWRON pin held low for 4 seconds or longer.
Have a great day,
Jose

What can happen if i have PWRON PIN HIGH and ISET PWRONRSTEN bit = 1 from SoC ?
Hi Nacho,
PWRONRSTEN bit = 1 would allow OFF mode after PWRON held low, but it will not turn OFF is PWRON pin is always HIGH.
Have a great day,
Jose
