Hi,

I have question about PF3000 RESETBMCU pin behavior.

 

According to the PF3000 data sheet, RESETBMCU is deasserted 2ms after all power ups.
It's call "default mode". i.e, OTP_PG_EN=0.
On the other hand, we can change to "fault mode" by writing OTP_PG_EN = 1.
We can't find out detailed explanation of this fault mode.

Please let me know :
Q1) In "fault mode", which power supply (all DC-DC, LDO ?) is specifically checked ?
Q2) What does PMIC specifically check? (Is the voltage appropriate?  or  over current?)
Best Regards,
Kanou
