Abstract
A circuit and a method are provided for protecting sensitive circuitry from over voltage and over current during a double fault situation. The circuit may be used in a portable electronic device, and may include an over voltage protection component and an over current protection component. The over voltage protection component may be coupled across power supply inputs of a load of the portable electronic device. The over current protection component is configured in the circuit to provide over current protection to the load of the portable electronic device at least when the over current protection component provides over current protection to the over voltage protection component.
