on PP3V3_S2, in diode mode i have 0.04 and 30Ohm in RES mode on LC710, with P3V3S2_PWR_EN = 0V and PP3V3_S2 = 0V
I view on boardview PP3V3_S2 must have 0.42 in diode mode
This is a short ? or normal ?...Leave a comment:

Thanks for repply
USBC0_CC1 = 0.597 on CF413
USBC0_CC2 = 0.597 on CF414
USBC1_CC1 = 0.597 on CF513
USBC1_CC2 = 0.597 on CF514
Mesure on usb c contact
USB0 :
CC1 = 0,597
CC2 = 0,597
USB1 :
CC1 = 0,598
CC2 = 0,598

A2338 - 820-02020 5V 0.370A, 20V 0.018A
Hi all, I am working on a MacBook logic board # 820-02020. It is stuck on 5v
PPVBUS_USBC0 = 5V
PPVBUS_USBC1 = 0V
PPDCIN_USBC_AON =5V
UF500 CD3217B12 :
PP3V3_UPC1_LDO = 3.26V
PP1V5_UPC1_LDO_CORE = 1.56V
UF400 CD3217B12 :
PP3V3_UPC0_LDO = 3.26V
PP1V5_UPC0_LDO_CORE = 1.56V
PPBUS_AON = 12.19V
If i plug a second USBC on the other port , no matter which one, PPVBUS_USBC0 = 5V, PPVBUS_USBC1 = 20.1V, PP3V3_UPC1_LDO = 3.26V, PP1V5_UPC1_LDO_CORE = 1.56V, PPDCIN_USBC_AON =5V
What is causing...
