7.3.1.2 PPHV Reverse Current Protection (RCP)

When the PPHV power path is enabled, the RCP circuitry monitors the voltage across the path. If the RCP monitor detects VPPHV - VVBUS ≥ VRCP_THRES_PPHV, the PPHV path will be disabled preventing additional current flow from PPHV to VBUS. The power path will be completely disabled and remain disabled as long as the RCP condition persists. After the RCP event, the PPHV path will automatically re-enable. FLT is not asserted when a reverse current protection event occurs on the PPHV path.
