macbook pro 16" m2 pro- A2780 - 820-02890 stuck at 5v - 0A on all usb port and magsafe.
all voltage:

PPBUS_AON = 0V , diode : 0,4
PP3V3_AON = 0V
PPVIN_P3V8AON 0V
PPDCIN_AON_CHGR = 5V
PPVBAT_AON_CHGR_REG = 0V
so U5200 not do the job
on u5200 :
PP5V_CHGR_SW = 4.5 v
CHRG_GATE_Q1 = 0V
1V8_SDA = 0V
​1V8_SDC = 0V
​
i check u5200 diode on PHASE and LX pin -> 0.4
i don't understand something ,
sda and scl in u5200 are pulup by 1V8_S2 ( 0V)
so can not communicate .
1V8_S2 are...
