I understand that there are two types of states during Fast Charge.
① VBAT = 3.0 ~ VSYSMIN: FastCharge (LDO mode)
② VBAT> VSYSMIN: FastCharge (BATFET is fully ON)
Is there a way to distinguish between the above two states?

Kagawa

HI, Kagawa,
You can check the charge status register 0x21/20.
When VBAT<VSYSMIN, it is pre-charge with LDO mode; 0x21 bit 1=1
When VBAT>=VSYSMIN, it is in fast charge, 0x21 bit 2=1.
