Abstract
An integrated circuit with a hot-plug protection circuit includes input pins and an output pin. The input pins are electrically coupled to a common node in the hot-plug protection circuit via respective electrical connections. The integrated circuit includes clamping circuitry coupled between the common node and the output pin, the clamping circuitry activatable as a result of a voltage spike applied across the clamping circuitry. The plurality of electrical connections and the clamping circuitry provide respective current discharge paths between the input pins in the input pins and the output pin, the respective current discharge paths configured to become conductive as a result of a voltage spike applied to any of the input pins in the plurality of input pins being transferred to the common node via the respective electrical connection in the plurality of electrical connections electrically coupling said any of said input pins to the common node.
