Hi Team,
Customer is using BQ24392.
1. VBUS always be 5V.
2. USB device here is UFP, DP default pull up to 3.3V by 1.5Kohm and DN default is floating.
3. GOOD_BAT always pull up to 3.3V after VBUS on.
4. In this case, we find CHG_AL_N = 0, CHG_DET = 0 and SW_OPEN =0.
For this case, which device is for above conditions? Standard charging port? Is the switch status connected?
Form the d/s table 1 detection table, it is not define this scenario. Would you please review and provide your comments?
BR,
SHH
