Yes, between 27/28 of U7100 resistance is 20,1 ohms

Re: MacBook Air 820-00165-A PPBUS-G3H <1V
Sorry, my mistake,
PPDCIN_G3H = 15,04V and also PPDCIN_G3H_ISOL
PPDCIN_G3H_INRUSH = 0,9V
CHGR_SGATE_DIV = 0,9V
PP5V1_CHGR_VDD = 5,14V
PP5V1_CHGR_VDDP = 5,14VLeave a comment:

Re: MacBook Air 820-00165-A PPBUS-G3H <1V
Removed fuse F7140 still have low voltage on ppbus_g3h
checked PPDCIN_G3H, 1,7V goes down to 0,8V
PPDCIN_G3H_ISOL : 15V
hope to find the sort :-)Last edited by Gpl; 08-07-2020, 12:29 PM.Leave a comment:
