TURN OFF PF3001A7 from SoC SW

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
