Protection circuitry configured to protect an electrical load from both overvoltage and overcurrent and includes a recovery period timer configured to set a recovery time. The recovery time allows a system, including a power supply, voltage regulator, protection circuitry and electrical load to dissipate heat and reset components. The protection circuitry is configured to monitor downstream performance of the electrical load and disconnect upstream power based on a downstream failure or other performance characteristics. The protection circuitry may include a downstream overvoltage sensing circuit that controls a current source. The current source injects current into an overcurrent protection loop in the protection circuitry that includes the configurable recovery period timer. In this manner both an overvoltage and an overcurrent event may take advantage of the configurable recovery period timer without the need for a separate time delay circuit.
