A lighting driver, comprising: a primary side and a secondary side separated by a galvanic barrier, wherein the secondary side includes a storage circuit configured to be electrically connected in parallel with a load configured to be driven by the lighting driver; a fault protection system comprising: a fault detection circuit on the secondary side configured to declare a fault mode by issuing a shutdown signal (Sig SD) in response to fault detection on the secondary side; an isolated control circuit configured to deliver the shutdown signal from the secondary side to the primary side to shut the primary side down during the fault mode without violating the galvanic barrier, wherein the storage circuit is configured to deliver an auxiliary current to the isolated control circuit during the fault mode; an auxiliary power circuit on the secondary side having an output node and configured to provide the auxiliary current from the output node to the fault detection circuit during the fault mode; and a switch circuit on the secondary side configured to connect the isolated control circuit to the auxiliary power circuit during the fault mode; and wherein the switch circuit further comprises a first transistor that turns on in response to the shutdown signal generated by the fault detection circuit and a second transistor that turns on in response to the first transistor turning on, the second transistor allowing the auxiliary current to flow from the isolated control circuit to the output node of the auxiliary power circuit; wherein the fault detection circuit is further configured to clear the fault mode in response to at least one of expiration of a shutdown timer, a successful fault mitigation, and a restart counter being less than a permanent shutdown threshold value. a primary side and a secondary side separated by a galvanic barrier, wherein the secondary side includes a storage circuit configured to be electrically connected in parallel with a load configured to be driven by the lighting driver;
