Abstract
A capacitance discharge limiter in which a DC transition protection circuit is provided in a circuit that includes a discharge circuit (which may be a power limiter) between a source and a receiver, with a capacitor situated between the source and the discharge circuit. The DC transition protection circuit is coupled to a reference voltage and to the control voltage input of the discharge circuit, and also between the capacitor and the discharge circuit at a node. The DC transition protection circuit detects the existence of an excess DC or low frequency (typically less than about 1 MHz) voltage potential at the node caused by charge on the capacitor, and regulates the control voltage so as to enable the discharge circuit to discharge the capacitor to protect the receiver.
