During OTG operation, BQ25638 uses two comparators to sense output overvoltage at VBUS and PMID. If either VBUS or PMID voltage rises above their OVP threshholds, the converter stops switching and attempts to discharge the voltage.
If the OVP condition persists on VBUS or PMID, OTG_FAULT_FLAG is set to 1, OTG_FAULT_STAT transitions to 1 and the converter powers down into a fault condition and the device exits from OTG mode by setting EN_OTG = 0.
