Abstract

A line protector circuit comprises an external side switch circuit coupled to an external circuit node of the line protector circuit, an internal side switch circuit coupled in series to the external side switch circuit and an internal circuit node of the line protector circuit, a high supply circuit node and a low supply circuit node, and switch control circuitry configured to deactivate the internal side switch circuit and divert a bias current from the external side switch to the low supply circuit node when the external voltage exceeds a high supply voltage of the high supply circuit node.
