Abstract: According to an embodiment, a transient voltage protection circuit includes a first integrated circuit including an input node, an output node, a first transient voltage protection component coupled between the input node and a reference voltage node, and an impedance element coupled between the input node and the output node. The first transient voltage protection component has a first dynamic resistance and the output node is configured to be coupled to an electrostatic discharge (ESD) protection component having a second dynamic resistance that is greater than the first dynamic resistance.
