7.4.5.1 Fault Types

Table 3 summarizes the various fault types available and when the FLT shall be asserted.

Table 3. Fault Types

Fault Name Fault FLT Description
VBUS_UVLO VBUS undervoltage Lockout Hi-Z If VBUS supply is below the VBUS UVLO threshold, the PPHV path is disabled automatically if enabled or remains disabled. If the SNK state is selected to be entered, the device will remain in the DISABLED state until the UVLO event is removed. If the SNK state has been entered successfully and a UVLO event occurs, the PPHV path is disabled automatically.
VBUS_OVP(1) VBUS overvoltage Protection Low If the SNK state is selected to be entered or device currently is in the SNK state and the VBUS supply rises above the VBUS OVP threshold, the PPHV path is disabled automatically and the FLT pin will be asserted.
VBUS_RCP VBUS Reverse-Current Protection Hi-Z If the SNK state is selected to be entered or device currently is in the SNK state and a reverse-current condition is detected, the PPHV path is disabled automatically, but the FLT is not asserted.. If the reverse-current condition is removed, the PPHV path will automatically re-enable.
PPHV_OVT PPHV overtemperature Protection Low If the SNK state is selected to be entered or device currently is in the SNK state and the local temperature of PPHV power path exceeds TSD_PPHV_R, the PPHV path is disabled automatically and the FLT pin will be asserted. PPHV power path will remain disabled until temperature falls below TSD_PPHV_F.
